Let's check every choices until one choices satisfy the graph :
Choice A is just a translation of -5 units or 5 units to the left
If we look at the graph between A"B"C" and A'B'C'
A"B"C" is 5 units to the left of A'B'C'
Therefore Choice A is True!
The correct answer is A.
No need to check for the other choices since you got a true statement at the first Choice.
IF in case that A is False, then you need to check the other choices.
