A. 26 and 99 is the correct answer.

26= 213
99= 3^(2)11
GCF (26,99)= 1
Because GCF (26,99)= 1, 26 and 99 are relatively prime.

Hope this would help~

Answer=A

Two numbers are relatively prime if they have no common factors (aside from 1). So lets solve for the factors of the number to see if they are relatively prime...

A. Relatively Prime 
26=1,2,13,26
99=1,3,9,11,33,99

B. NOT RELATIVELY PRIME
90=1,2,3,5,6,9,10,15,18,30,45,90
117=1,3,9,13,39,117

C. NOT RELATIVELY PRIME
100=1,2,4,5,10,20,25,50,100
202=1,2,101,202

D. NOT RELATIVELY PRIME
201=1,3,67,201
444=1,2,3,4,6,12,37,74,111,148,222,444
