C Correct answer
Explanation

Let principal be P and rate be R%. Given: 4-year simple interest = P/4, so 4PR/100 = P/4. Solving: R = 100/16 = 6.25%. For 2 years at same rate: Amount = P + (2 × 6.25/100)P = 1.125P. Setting 1.125P = 2250 gives P = 2000. Check: 2-year SI on Rs.2000 at 6.25% is Rs.250, so amount = Rs.2250.
