If A and B are positive integers greater than 1 such that the GCD of A and B is 1, then which of the following must be true?
I. A and B are prime numbers.
II. A and B are consecutive numbers.
III. A and B do not have a common prime factor
IV. The product AB has two prime factors
V. A and B have the opposite even-odd nature
A. I & II only
B. III only
C. I, V only
D. I, II, III, V only
E. I, II, III, IV & V
OA is B
I got this question through process of elimination. Once i was able to figure out that I. is not the answer, i was able to eliminate A,C,D, and E which has I. So, i selected B.
However, while i was reviewing, i was not able to understand V.
V. says A and B have opposite even-odd nature. To this statement i undertood that A = 2 and B = 9, which is TRUE
But, It could also be A = 3 and B = 5, which is FALSE.
Kindly, please let me know about V.
Thanks
