Read the passage given below and answer question:
In the last 10 years much has been learned about the molecular structure of elemental sulfur. It is now known that many different types of rings are sufficiently metastable to exist at room temperature for several days. It is known that at high temperature, the equilibrium composition allows for a variety of rings and chains to exist in comparable concentration, and it is known that at the boiling point and above, the vapor as well as the liquid contains small species with three, four, and five atoms.
The sulfur atom has the same number of valence electrons as oxygen. Thus, sulfur atoms `S_2` and `S_3` have physical and chemical properties analogous to those of oxygen and ozone. `S_2` has a ground state of 38 `sigma 3s^2 sigma "*"3s^2 sigma 3pz^2 pi 3px^2=pi3py^2 pi"*"3px^1=pi"*"3py^1.S3` , thiozone has a well- known uv spectrum, and has a bent structure, analogous to its isovalent molecules `O_3, SO_2`, and `S_2O`. The chemistry of the two elements, sulphur and oxygen, differs because sulfur has a pronounced tendency for catenation. The most frequently quoted explanation is based on the electron structure of the atom. Sulfur has low-lying unoccupied 3d orbitals, and it is widely believed that the 4s and 3d orbitals of sulfur participate in bonding in a manner similar to the participation of 2s and 2p orbitals in carbon.

In the following question, a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the choices on the basis of the above passage.
Assertion: Sulphur belongs to same group in the periodic table as oxygen.
Reason: `S_2` has properties analogous to `O_2`.

Options

A. Assertion and reason both are correct statements and reason is correct explanation for assertion.
B. Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C. Assertion is correct statement but reason is wrong statement.
D. Assertion is wrong statement but reason is correct statement.

Answer

To solve the question based on the provided passage, we need to analyze both the assertion and the reason given.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Sulfur belongs to the same group in the periodic table as oxygen."
- From the passage, we know that sulfur (S) and oxygen (O) are both part of Group 16 in the periodic table, often referred to as the chalcogens. Therefore, this assertion is **true**.

2. **Understanding the Reason**:
- The reason states that "S2 has properties analogous to O2."
- The passage mentions that sulfur atoms `S2` and `S3` have physical and chemical properties analogous to those of oxygen and ozone. Since `O2` is the molecular form of oxygen, this statement is also **true**.

3. **Evaluating the Relationship Between Assertion and Reason**:
- While both the assertion and reason are true, we need to determine if the reason is the correct explanation for the assertion.
- The assertion about sulfur belonging to the same group as oxygen is based on their position in the periodic table, while the reason discusses the properties of `S2` in relation to `O2`.
- The reason does not directly explain why sulfur is in the same group as oxygen; it only provides information about their molecular forms. Therefore, the reason is not the correct explanation for the assertion.

4. **Conclusion**:
- Both the assertion and reason are true, but the reason is not the correct explanation for the assertion. Thus, the correct answer is that both statements are true, but the reason does not explain the assertion.

### Final Answer:
Both the assertion and reason are true, but the reason is not the correct explanation for the assertion.
