Consider the following statements.
All the elements of d-block are non-metals.
Non-metals are react with oxygen to form basic oxide.
Select the correct statements.

Options

A. Only I
B. Only II
C. Both I and II
D. None of the above

Answer

To solve the question, we need to analyze the two statements provided and determine their validity.

### Step 1: Analyze the first statement
**Statement 1:** All the elements of d-block are non-metals.

- The d-block of the periodic table consists of transition metals, which are characterized by their ability to form variable oxidation states and colored compounds.
- The elements in the d-block include metals such as iron (Fe), copper (Cu), and gold (Au), among others.
- Therefore, this statement is **false** because d-block elements are primarily metals, not non-metals.

### Step 2: Analyze the second statement
**Statement 2:** Non-metals react with oxygen to form basic oxides.

- Non-metals typically react with oxygen to form oxides that are acidic or neutral in nature.
- For example, carbon reacts with oxygen to form carbon dioxide (CO2), which is an acidic oxide, and sulfur reacts with oxygen to form sulfur dioxide (SO2), which is also acidic.
- Therefore, this statement is **false** because non-metals do not form basic oxides when they react with oxygen.

### Step 3: Conclusion
Since both statements are false, we conclude that there are no correct statements among the options provided.

### Final Answer
The correct answer is: **None of these.**
