Explanation

The RBI Financial Inclusion Index (FI-Index) was introduced in August 2021 to assess how well people across India can access and use formal financial services. It covers areas including banking, insurance, investments, postal services and pensions.

The index is based on three key dimensions:

1. Access (35%) — Availability of financial infrastructure such as bank branches, ATMs and PoS terminals.
2. Usage (45%) — Extent to which people actually use services such as credit, savings, insurance and digital payments.
3. Quality (20%) — Qualitative aspects such as financial literacy, consumer protection and service gaps.

Option A — Incorrect: Credit, insurance and pension are covered within the index, but they are not its three main dimensions.

Option B — Incorrect: GDP contribution has no role as an FI-Index dimension. Financial literacy is included under Quality.

Option C — Correct: The three dimensions are Access, Usage and Quality.

Option D — Incorrect: Affordability and Transparency are not separate FI-Index dimensions.

Therefore, Option C is the correct answer.
