D Correct answer
Explanation

You first get 75 chocolates for Rs. 75. Then you exchange the 75 wrappers of these 75 chocolates for 25 chocolates. You keep wrapper of 1 chocolate with you and exchange the 24 wrappers for 8 chocolates. Now you have 9 wrappers with you (8 + 1 you saved before) which you exchange for 3 chocolates. Now, you exchange wrappers of these 3 chocolates for 1 more chocolate. Hence, the total number of chocolates you end up getting is 75 + 25 +  8 + 3 + 1 = 112
