Correct Option (d)
Assertion (A) states that reservation of thirty-three percent of seats for women in Parliament and State Legislature does not require any Constitutional amendment. This statement is false. Any provision for reservation of seats in legislative bodies, such as Parliament and State Legislatures, fundamentally alters the electoral structure and representation defined by the Constitution. Similar to reservations for Scheduled Castes and Scheduled Tribes (Articles 330 and 332), a constitutional amendment under Article 368 is necessary to introduce such a measure for women. Historical attempts, like the Women's Reservation Bill, have consistently been introduced as constitutional amendment bills.
Reason (R) states that political parties contesting elections can allocate thirty-three percent of seats they contest to women candidates without any Constitutional amendment. This statement is true. The allocation of election tickets to candidates is an internal policy decision of political parties. There is no constitutional or legal bar preventing parties from voluntarily deciding to field a certain percentage of women candidates. This action falls within the operational autonomy of political parties and does not involve amending the Constitution.
Since Assertion (A) is false and Reason (R) is true, option (d) is the correct choice.
Incorrect Options
Options (a), (b), and (c) are incorrect because they either incorrectly evaluate the truthfulness of Assertion (A) or Reason (R), or incorrectly describe the relationship between them. Assertion (A) is definitively false as constitutional amendment is required for seat reservation in legislatures, and Reason (R) is true as party ticket allocation is an internal matter. Therefore, options suggesting both A and R are true, or A is true, are incorrect.
