Answer:
A
The answer would be A because what is 156- 19=137 so we now take out number 2/B
137-19=118 So that means we can eliminate number 3/c that says 119 so that's out now.
And for last number the 3rd number to subtract is what is 118-19=99 so we just eliminated number 4 that says 98.
And the only number that followed our answers and ad the same answer for us was A so lets go with A.
Hope this helps have a great day:)
