B Correct answer
Explanation

The dealer gains 25% profit while claiming to sell at cost price. This means he gives only 100/(100+25) = 100/125 = 4/5 of the actual weight. For 1 kg (1000 gm), he substitutes 1000 × 4/5 = 800 gm. Profit = (1000-800)/800 = 200/800 = 25%. Therefore, he substitutes 800 gm for every kilogram.
