(1) k + 3 > 0
(2) \(k^4 \leq 0\)


B. K^4 can never be less than 0,so k=0

Answer has to be E from B we get k = 0 and o is not an integer.

Statement 1
- \(k + 3 > 0\), so \(k > -3\)
- Not sufficient.

Statement 2
- \(k^4 <= 0\)
- If K (+), no positive numbers satisfy this inequation.
- If K (-), no negative numbers satisfy this inequation.
- In fact, \(k^4\) cannot be negative for any numbers, so only \(k=0\) will satisfy.
- Hence, it sufficient.

B.

0 is neither positive nor negative even integer.

Bunuel-your explanation could convey an incorrect meaning here. I know you mean to say ' 0 is neither positive nor negative' but that it is an integer
This is not what your sentence means ;)

1) K can take any positive value or 0 or negative value such that -3 < k < 0

Clearly insufficient

2) K^4 is ALWAYS bob-negative value it can't be negative. Only value here is k = 0

Sufficient

Answer: B
