Section 80D of the Income Tax Act, 1961 can be understood by breaking it into three separate questions: who is covered, how much can be claimed, and what conditions attach to the claim.
Put together, this shows the deduction exists, is available to ordinary taxpayers and not just senior citizens, and is capped and conditional rather than open-ended. That rules out the option denying the deduction altogether, the option restricting it only to senior citizens, and the option claiming there is no monetary limit.
The correct answer is deduction is allowed subject to prescribed limits and conditions.
Three of the four options each get one part of Section 80D wrong, either its existence, its scope, or its ceiling. Testing the provision against each of those three errors, in turn, isolates the correct option.
Each of the three incorrect options fails a different, specific test drawn directly from how the provision operates, existence, scope, or ceiling, leaving only one option standing.
So the correct answer is deduction is allowed subject to prescribed limits and conditions.
