Because of polio attack in his childwood his both the legs inoperative permanently.

I want to claim deduction u/s 80dd of Income tax act, some persons referred me to take Jeevan Aadhar policy offered by Lic.

Please tell me deduction u/s 80dd can only avail if i am going to take above policy or similar investment in any manner or i can avail a lumpsum amount as deduction if i can get a certificate from medical practisioner.

Please urgently clarify.
