Detailed Solution:
The correct answer is “Indira Vikas Patra”.
National Savings Certificate (NSC), Public Provident Fund (PPF), and National Savings Scheme (NSS) are all eligible for tax deductions under Section 80C of the Income Tax Act. Indira Vikas Patra (IVP), on the other hand, does not offer any tax benefits. The interest earned on IVP is fully taxable.
