Under the NPS Vatsalya Scheme Guidelines, 2025, which of the following is an option available to the subscriber on attaining 18 years of age?

NPS Vatsalya was launched in September 2024 following the announcement in the Union Budget 2024-25, and PFRDA notified the NPS Vatsalya Scheme Guidelines, 2025 to lay down its detailed rules. The account is opened in the minor's name and operated by a parent or guardian, with the minor as the sole beneficiary. On attaining 18, the subscriber must complete fresh KYC and gets a window up to age 21 to choose one of three options: continue in NPS Vatsalya up to 21, shift the corpus to NPS Tier-I (All Citizen Model or another eligible model), or exit. On exit, full withdrawal is allowed if the corpus is below ₹8 lakh; otherwise up to 80% can be taken as a lump sum and at least 20% must be used to buy an annuity. If no option is chosen by 21, the account moves to a higher-equity scheme under the Multiple Scheme Framework (MSF). Options (a) to (d) are incorrect because the corpus is not paid to the guardian, not moved to APY, not frozen, and does not have to be fully annuitised.
