The object of section 57 of the Transfer of Property Act, 1882 is to:

Section 57 of the Transfer of Property Act, 1882, deals with the sale of encumbered property.

An encumbered estate is a property burdened with some charge or liability, such as a mortgage, lien, or other encumbrance that affects its ownership or transfer.

The primary objective of Section 57 is to facilitate the sale of such encumbered properties by providing a mechanism to deal with the existing encumbrances.

Option A correctly states the object of Section 57. The section aims to simplify the process by allowing the sale to proceed even with existing encumbrances, often by providing a way for the buyer to acquire a clear title, free from these burdens. This is done through procedures outlined in the Act, which deal with the payment or discharge of the encumbrances from the sale proceeds.

Option B is incorrect as it directly contradicts the purpose of Section 57.

Option C is incorrect because it incorrectly supports the false statement in Option B.

Option D is also incorrect as Option A accurately describes the object of Section 57.
