The answer is: D
Explanation
The correct option is D: The condition is void, and B may or may not live in the house, as per his discretion.
Here's the explanation:
The principle stated in Section 11 of the Transfer of Property Act, 1882, allows for the transferee to enjoy or dispose of the property as if there is no condition when an absolute interest is created in the property by one person in favor of the other, but the terms of transfer direct that such interest be applied or enjoyed in a particular manner.
In this case, A has made an absolute gift of the house to B but with the condition that B shall reside in it. However, Section 11 of the Transfer of Property Act makes it clear that when such a condition restricts the transferee's rights to a significant extent, the condition is considered void, and the transferee has the discretion to live in the house or not.
Therefore, Option D is the correct choice because the condition is void, and B is not legally obligated to live in the house as per A's direction.
