The International Securities Identification Number (ISIN) is a globally recognized unique identifier for securities, including shares, bonds, and debentures, in electronic or dematerialized format.
In India, the National Securities Depository Limited (NSDL) is responsible for allocating ISINs to dematerialized shares. NSDL assigns these ISINs to securities to streamline their electronic identification, settlement, and transfer.
Explanation of Other Options:
(A) NSE: The stock exchange does not issue ISINs.
(B) RBI: The Reserve Bank of India oversees banks and financial institutions, not securities identification.
(D) SEBI: The Securities and Exchange Board of India regulates the securities market but does not assign ISINs.
Therefore, option (C) is the correct choice.
