The question asks "What MUST be true?"
So, if we can find a case in which a statement is NOT true, we can eliminate it.
A. a > b
We're told that a/b > 0
So, it COULD be the case that a = 1 and b = 2 (since 1/2 > 0)
If a = 1 and b = 2, then the statement that a > b is NOT TRUE
ELIMINATE A
B. b > 0
We're told that a/b > 0
So, it COULD be the case that a = -3 and b = -2 (since -3/-2 > 0)
If a = -3 and b = -2, then the statement that b > 0 is NOT TRUE
ELIMINATE B
C. ab > 0
We're told that a/b > 0, which means EITHER a and b are both positive OR a and b are both negative
If a and b are both positive, then ab > 0
If a and b are both negative, then ab > 0
In BOTH possible cases ab > 0, which means statement C MUST be true.
Answer: C

B. b > a
We're told that a/b > 0
So, it COULD be the case that a = 3 and b = 2 (since 3/2 > 0)
If a = 3 and b = 2, then the statement that b > a is NOT TRUE
ELIMINATE B
C. ab > 0
We're told that a/b > 0, which means EITHER a and b are both positive OR a and b are both negative

Actually !!!!!
B. b > 0, not b > a, that you get to solve.
