Hi there, its just a matter of trial and error as you know it has to be greater then 20 then the numbers you test must add together to be greater then 20.
a) 5+16 = 21, 5*16 = 80
b) 10+11 = 21, 10*11 = 110
c) 15+6 = 21, 15*6 = 90
d) 20+2 = 22, 20*2 = 40
e) 50+1 = 51, 50*1 = 50
so as you can see 20 would be one of the integers so your answer is D
