What is a 'Depository Participant' (DP)?

[ A ]A computer software terminal used exclusively by stock exchange pit traders.
[ B ]A foreign central bank that holds sovereign debt reserves.
[ C ]An individual retail investor who buys at least 1,000 shares in an IPO.
[ D ]An agent or intermediary registered with SEBI (such as a bank, financial institution, or stockbroker) through whom an investor opens a Demat account and interacts with the Depository.[ CORRECT ]
Takeaway

A Depository Participant is the SEBI-registered intermediary — typically a bank, broker, or financial institution — through which an investor actually opens a demat account and transacts with a depository like NSDL or CDSL.

Derivation
Depositories (NSDL/CDSL) do not deal with retail investors directly; they operate through a network of DPs who act as the customer-facing agents, verifying KYC, opening and maintaining demat accounts, and routing debit/credit instructions to the depository's central system. This two-tier architecture (Depository -> DP -> Investor) mirrors how a bank's central ledger is accessed through branches, and the exam tests this layered structure because candidates often conflate the depository (the central record-keeper) with the DP (the client-facing access point) — they are legally and functionally distinct entities under the Depositories Act.
Why the others fail
A — A computer software terminal used exclusively by stock exchange pit traders.
A DP is a registered corporate or institutional legal entity performing custodial functions, not a piece of trading software confined to exchange floor terminals.
B — A foreign central bank that holds sovereign debt reserves.
Foreign central banks manage sovereign monetary policy and reserves; they have no role as SEBI-registered domestic securities intermediaries.
C — An individual retail investor who buys at least 1,000 shares in an IPO.
A retail investor who buys shares is a beneficial owner (client) of a demat account, not the intermediary that opens and administers such accounts.
