Is |xy| = 12?
(1) (y + 4)(x - 3) = 0
The sentence states either Y = -4 or X = 3,
But we don't know for sure that they co-exist together.
(Not Sufficient)
(2) y = 4
We don't know the value of X here
(Not Sufficient)
Combining both,
Put, Y = 4 in sentence 1
Then x has to be 3 to satisfy statement 1.
Hence, |XY| = |3*4| = 12
(Sufficient)
Answer is C
