Options

A. Statement-1 is True, Statement-2 is True,Statement-2 is a correct explanation for Statement-1.
B. Statement-1 is True, Statement-2 is True,Statement-2 is NOT a correct explalanation for Statement-8
C. Statement-1 is True, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Answer

To analyze the statements provided in the question, we will evaluate each statement regarding Helium and Beryllium.

### Step 1: Evaluate Statement 1
- **Statement 1**: Helium and Beryllium both are chemically inert.
- Helium (He) is a noble gas with the electronic configuration of 1s². Noble gases are known for their chemical inertness due to their complete valence shell, which makes them stable and unreactive.
- Beryllium (Be), on the other hand, has the electronic configuration of 1s² 2s². While it is less reactive than many metals, it is not completely inert. Beryllium can react with acids and other substances, indicating that it is chemically reactive.

**Conclusion for Statement 1**: This statement is **false** because Beryllium is not chemically inert.

### Step 2: Evaluate Statement 2
- **Statement 2**: Helium and Beryllium have similar outer electronic configuration of the type ns².
- Helium has an outer electronic configuration of 1s².
- Beryllium has an outer electronic configuration of 2s² (with the inner shell being 1s²).
- Although they do not have the same principal quantum number for their outermost electrons, they both have a filled s subshell (1s² for Helium and 2s² for Beryllium).

**Conclusion for Statement 2**: This statement is **true** in the context of both elements having filled s orbitals in their outermost shell configurations.

### Final Conclusion
- Statement 1 is **false**.
- Statement 2 is **true**.

Thus, the correct answer is that Statement 1 is false, and Statement 2 is true.
