Inflation-Indexed Pension Plan is not a type of pension plan in India. The other three options - Defined Benefit Plan, Defined Contribution Plan, and Hybrid Plan - are all types of pension plans that are offered by various companies and organizations in India. A Defined Benefit Plan provides a specific retirement benefit that is predetermined by a formula, while a Defined Contribution Plan provides a benefit based on the contributions made and investment performance. A Hybrid Plan combines elements of both Defined Benefit and Defined Contribution plans.
