D Correct answer
Explanation

At 5% loss, selling price is 0.95 × CP. At 5% gain, selling price is 1.05 × CP. The difference between these two selling prices is Rs. 80, which equals 0.10 × CP. Solving gives CP = Rs. 800. This is a standard profit-loss problem where the price gap corresponds to the percentage difference.
