LIC POLICIES premium paid eligible to get the benefit u/s 80C. I think all the policies of LIC eligible to get the benefit under the aforesaid section.
Normally term plans are most tax efficient. In case of other policies, If your premium exceeds 10 percent of sun assured your deduction u/s 80c will be limited to 10 percent of the sum assured. Also the maturity proceeds except in case of death will be taxable. So only take term plans.
