C
63 is the sum of all their ages, meaning that this is their ages added altogether, eliminating A and D as answer choices since those show multiplication instead of addition. Next, the problem states that the three consecutive integers are odd. This statement eliminates B as an answer choice since it’s using three consecutive even integers. This leaves C as your final answer.
And it’s not that you have a thick skull, math can just be tricky sometimes, but you’ll get it! good luck! :)
