Explanation:

- Statement 1: The powers of the Central and State Governments are clearly laid down.

- This is a key feature of a federal state. A written constitution typically provides a clear division of powers.

- Statement 2: It has an unwritten Constitution.

- An unwritten constitution is more characteristic of a unitary state rather than a federal one. Federal states usually have a written constitution to outline the division of powers.

- Option 1: 1 only

- This option is correct. It only includes the first statement, which is true for federal states.

- Option 2: 2 only

- Incorrect, as federal states do not typically have unwritten constitutions.

- Option 3: Both 1 and 2

- Incorrect, as the second statement does not apply to federal states.

- Option 4: Neither 1 nor 2

- Incorrect, as the first statement is true for federal states.

Option 1: 1 only is the correct answer.
