Explanation

Items 1, 2, and 3 are correct:
– FCCBs (Foreign Currency Convertible Bonds) and GDRs (Global Depository Receipts) are foreign-currency equity-linked instruments that grant overseas holders an equity stake in Indian enterprises upon conversion, counting toward composite foreign direct investment.
– As per the Arvind Mayaram Committee guidelines on foreign investments, if a Foreign Portfolio/Institutional Investor (FPI/FII) holds 10% or more of the post-issue paid-up equity capital of a company, it is reclassified as Foreign Direct Investment (FDI).

Item 4 is incorrect: Non-Resident External (NRE) deposits represent foreign-currency deposits placed by NRIs in domestic banks. These are external debt liabilities and banking capital flows, not equity capital or FDI.

Thus, 1, 2, and 3 are included — Option A.
