Concept:
- A Demat account only stores and transfers securities in electronic form; it does not itself execute trades or move cash, since those functions belong to a separate trading account linked with the broker.
- Testing each option against what a Demat account actually does, and matching the option that fails to a different real account or agreement, is a reliable way to find the correct choice by elimination.
Step 1: Recall the meaning of dematerialisation.
Dematerialisation is the process of converting physical share certificates into an electronic record, so a Demat account is the electronic store for these converted securities and lets them move between investor accounts during settlement.
Step 2: Check option (b), entering into an agreement with a broker.
Signing an agreement with a stockbroker happens when opening a separate trading account with that broker, not when opening a Demat account, so option (b) is ruled out.
Step 3: Check option (c), making payment to the stock exchange for a purchase.
Payments for buying securities move through a bank account linked to the trading account; a Demat account holds securities, not cash, so option (c) is ruled out.
Step 4: Check option (d), enabling cash transactions in the securities market.
Cash movement also happens through the linked bank and trading accounts, not through the Demat account, so option (d) is ruled out as well.
Step 5: Match the remaining option.
With options (b), (c), and (d) ruled out, the function that is left, holding and transferring securities electronically, is exactly what option (a) describes.
Final Answer: Option (a): for holding and transferring securities in the Demat form.
