Is the NPS for private employees or only government employees?
You can avail the benefit of only (100,000 - Your PF Contribution) under Sec 80C.
Investment Options Under Sec 80C
Under Sec 80C, for heads, all members have already mentioned the options except the most secure BANK FIXED DEPOSIT for 5 years. Take a bank FD of any nationalized bank, e.g., SBI, for 5 years, and that amount is exempt under Sec 80C.
Medical Insurance Premium Under Sec 80D
Under Sec 80D, Medical Insurance Premium, you can claim a total of 35,000 (15,000 - Self Dependents, 20,000 - for parents if parents are senior citizens, else 15,000 for parents if they are not senior citizens; now, age above 60 is a senior citizen).

House Rent Allowance (HRA)
What about HRA (House Rent Exemption)? What are you doing?
Financial Planning Advice
And one piece of advice, rather than just investing blindly to save tax, it is better to pay tax. In my office, many employees just leave the investments like that. They say, for saving 3,000 Rs, if I need to invest 30,000, I better not invest. That is also very bad. So plan your financials as per your need and requirement so that tomorrow you may not feel that it would have been better if you had paid the tax, rather than locking the capital in some funds, MF, etc., especially MFs have risks.
