B Correct answer
Explanation

Cost price per orange in first batch = Rs 60/20 = Rs 3. Cost price per orange in second batch = Rs 60/30 = Rs 2. Average cost price = (3+2)/2 = Rs 2.5 per orange. Selling price = Rs 60/25 = Rs 2.4 per orange. Loss per orange = Rs 2.5 - Rs 2.4 = Rs 0.1. Loss percent = 0.1/2.5 × 100 = 4%.
