The correct answer is option (4)- A-III, B-IV, C-I, D-II.
| List I |
List II |
| A. Depositors |
III. NSDL |
| B. Dematerialisation |
IV. Converting physical shares into electronic form |
| C. Pay in day |
I. Cash paid or securities delivered |

II. T+ 2 (Trade + 2 grace days) |
A. Depositors - III. NSDL.
Depositors are individuals or institutions who hold securities in their dematerialized (electronic) form. They open accounts with a depository to hold these securities. NSDL (National Securities Depository Limited) is one of the two major depositories in India that helps in holding securities in electronic form and facilitates their transfer. The depository acts as a custodian of securities for the depositors.
B. Dematerialization -IV. Converting physical shares into electronic form.
Dematerialization is the process of converting physical share certificates into electronic form. This allows securities to be held in electronic accounts (demat accounts), which makes trading, transfer, and settlement of securities faster and more secure.
C. Pay-in day - I. Cash paid or securities delivered.
Pay-in day refers to the day on which investors or traders need to deliver the securities or funds that they have sold or committed to in a trade. This is the day by which the seller must deliver the securities (or the corresponding cash if the securities are in physical form) to the clearinghouse or counterparty.
D. Rolling Settlement System - II. T + 2 (Trade + 2 grace days).
Rolling Settlement System refers to the method of settling trades in the stock market, where the settlement of a trade takes place a few days after the trade date. The most common system is T+2, meaning that the settlement occurs two days after the trade date (i.e., the buyer must pay and the seller must deliver the securities within two working days after the trade). This system improves liquidity and reduces the risk of defaults. |
