Solution (By Examveda Team)

The question asks about Section 63A of the Transfer of Property Act, 1882, and when a mortgagor (the borrower) has to pay for improvements made to the property.
The section states the mortgagor is liable for the cost of improvements if they fall under specific reasons.
Let's break down the options:
Option (1): Necessary to preserve the property from destruction or deterioration - This means the improvements were needed to stop the property from being ruined or getting worse.
Option (2): Necessary to prevent the security from becoming inadequate - This means the improvements were needed to maintain the property's value as security for the loan.
Option (3): Done under the order of public authority such as a municipality - This means the improvements were required by a government body like a city council.
The question states that the mortgagor is liable to pay the cost of improvements only if they fall under any of the listed reasons.
All three options are valid reasons for the mortgagor to be responsible for the cost.
Therefore, the correct answer is A: All are equally relevant.
This is because all three conditions listed in the question are valid reasons, according to Section 63A, for the mortgagor to be liable for the cost of improvements.
