Answer:
The answer is D.
Explanation:
A could not be the answer beacuse 3 x 3 is 9. Add one more to that and you would get ten.
B could not be the answer because 4 x 3 is 12. Minus that by 2 ans you would get ten, not one.
C is not the answer either. 2 x 3 is 6. Minus that by one and you would get five, not three.
D is the right answer because 5 x 3 is 15. Add two to that and you would get 17.
As you can see, D is the right answer.
