{a, b, c, d}
What is the median of the list above?

(1) The product of no two elements of the list is negative -> [ 1, 2, 3, 4] or [1,1,1,1] NS

(2) The sum of the elements of the list is 0 -> [ -1,0,0,1] [ -2,-1,1,2] : NS

1 & 2 -> C
[ 0 0 0 0] Median = 0

+1 for C.

(1) The product of no two elements of the list is negative
The elements could be positive, zero, non-integer.
Insufficient

(2) The sum of the elements of the list is 0
The elements could be zero or mix of both positive and negative.
Insufficient

Combining both :
All the elements have to be zero in order to fit the condition.
Therefore, Median = 0
Sufficient

Hence, C.

(2) The sum of the elements of the list is 0

Here is my approach.
(1) The product of no two elements of the list is negative --> all the elements of the list have the same sign. The list could be (-1,-1,-1,-1) or (1,1,1,1) --> Not sufficient.
(2) The sum of the elements of the list is 0 --> The list could be (0,0,0,0) or (-1,-1,-1,3) --> Not sufficient.
(1)+(2) : only (0,0,0,0) satisfies --> median = 0 --> Sufficient.
Answer C.
