Since its 4,6 over to 4 and up to 6 the closest one to that mark would have to be   A. because it says over to 4 and up to 7.2 which is the closest of the choices that you have :) hope this helps

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
