Answer:
I think A
Step-by-step explanation:
Because if you change it from (43 + 60) + 40 to (60 + 40) + 43 = 143
You automatically know it is 143 because 60 + 40 is 100 + 43 = 143
And it wouldn't be D because that is already in a easy way the solve. The others looked to complicated to even attempt so it has to be A.

The set of two-digit primes is {11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97}
Of that list, the following primes are mirror images of each other
13 and 31
17 and 71
37 and 73
79 and 97
Note: we ignore 11 since 11 flips to 11 which is not distinct from its original
If you're looking for the largest prime of this form, then its 97
If you're looking for the largest gap, then subtract each pair
31-13 = 18
71-17 = 54
73-37 = 36
97-79 = 18
We see that 71 and 17 have the largest gap
