Which one is best for investment - LIC New Bima Gold & Jeevan Saral?

I am interested to invest Rs 15,000 yearly in LIC policy for approx. 20 years, so I had selected two LIC policies - New Bima Gold & Jeevan Saral.

Please advice which LIC policy is good new bima gold or jeevan saral & if I am going for jeevan saral then I should purchase a single policy or should I split it in 4 policy. What will be return after 15 to 20 years.

Or

Advice some LIC policy in which I can invest Rs 15000 per year for 20 years to get good returns.

First thing first - Insurance is for risk coverage not for investment.

Jeevan Saral - Endowment Plan
New Bima Gold - Money back plan

So it's like comparing apple with oranges.
