A mutual fund family, often referred to as a fund complex, consists of a group of mutual funds offered by a single investment company or sponsor.

If a policyholder loses their original insurance document, they must report the loss to the insurer. The insurer will then issue a duplicate policy document.

A robust financial system performs several vital roles: it mobilizes savings for large-scale investments, provides tools for risk management, facilitates the transfer of resources across time and space, and generates critical information that coordinates decentralized decision-making.

NABARD (National Bank for Agriculture and Rural Development) acts primarily as a development bank. It does not typically engage in direct lending to individual rural borrowers. Instead, it provides refinance facilities to commercial banks, regional rural banks, and cooperative banks, thereby enabling these institutions to extend credit to the agricultural and rural sectors.

Note: The provided answer key C suggests a-1, which contradicts standard banking classifications.
