The correct answer is (d). Retail trade.

Gambling and betting are illegal in India, and FDI is not allowed in these sectors.

The lottery business is regulated by the states in India, and FDI is allowed in some states but not in others.

Chit funds and Nidhis are financial institutions that are regulated by the Reserve Bank of India, and FDI is not allowed in these institutions.
