The LIC Saral Pension Scheme is notworth buying.
The best form of pension is systematic withdrawal plan from a mutual fund corpus under growth scheme.
Create as big a corpus as possible by investing via SIP in equity mutual funds - GROWTH option.
When you retire you can do SWP.
Since the amount withdrawn falls under long term gain , the maximum is tax rate is 10.4% above 1 lakh gain per financial year.
Any other form of pension (like SARAL) comes under ANNUITY scheme and is fully taxable.
Annuity returns are usually 5–6 % . With tax the rate is less than inflation.
Final note- Avoid all insurance pension schemes.
