D Correct answer
Explanation

If amount grows from Rs. 650 to Rs. 676 in one year, interest = Rs. 26. Rate = 26 ÷ 650 × 100 = 4%. Let principal be P, then P × 1.04 = 650, so P = 650 ÷ 1.04 = Rs. 625. Option A is incorrectly calculated as 650 × 2, option B is the first year's amount, and option C is a rough approximation.
