Hdfc unit link pension plus

Respected Sir,

I had bought 1 Unit Linked Pension Plus Plan of Hdfc in sept 2008, & I was paying 2 Lacs premium per year. I have paid premium for 3 years. and due to decerese in NAV of such policy I had stooped to pay premium . Later in year 2016 I had Surrender such policy and got 2.50 Lacs profit from such policy.

Total Premium Paid = 6 Lacs
Surrender Value = 8.50 Lacs

Please tell me tax treatment ??

If I should consider it as Long term capital gain ??

If yes then, Does Indexation benefit apply ??
