Correct Option
The Parliament (Prevention of Disqualification) Act, 1959, exempts several offices from disqualification on the grounds of 'Office of Profit'. This Act was enacted to clarify which offices would not lead to disqualification under Article 102(1)(a) and Article 191(1)(a) of the Constitution. Therefore, statement 1 is correct.
The Parliament (Prevention of Disqualification) Act, 1959, has been amended five times since its enactment to update the list of exempted offices and modify its provisions. Thus, statement 2 is correct.
Incorrect Options

Therefore, statement 3 is incorrect.
Option (B) is incorrect as statement 3 is factually inaccurate.
Option (C) is incorrect because while statement 2 is correct, statement 3 is incorrect.
Option (D) is incorrect because statement 3 is factually inaccurate.
