Option B is correct. According to the provided context, in the absence of any information regarding the specific ratio in which remaining partners acquire the retiring partner's share, it is assumed they acquire it in their old profit sharing ratio. Consequently, the new profit sharing ratio between the continuing partners remains the same as their old ratio. Since Abhishek and Rajat previously shared profits in the ratio of 5:3, their New Profit Sharing Ratio will remain 5:3.
