(1) x is a factor of 3y + 3.
(2) x is the least positive factor of y + 3.


Since the question stem gives us very little to go on, we have no choice but to go straight to the statement without any idea for what we're looking for.
In these cases we'll use the statements themselves to focus us in the right direction -- an Alternative approach.

(1) without information on y, we cannot say anything at all about x.
Insufficient.

(2) the least positive factor of any integer is always 1. so x = 1.
Sufficient.

(B) is the answer.
