msk0657 · Answer

Stat 1: y = -4 is sufficient to answer.

Stat 2: y < 0 , we can take -1 to infinite values...Insufficient.

Option A.

abhimahna · Answer

Answer is A.

Statement 1 is of the form  (y+4)^2 = 0  or y=-4. Sufficient.

Statement 2 : No distinct value of y is known. Hence Insufficient.

rahulvedanta · Answer

Statement 1 is alone sufficient..

y^2 + 8y + 16 = 0
(y+4) ^2 = 0
y = -4

Statement 2 alone is insufficient as y can take any value less than 0.

Hence, option A is right.
