I would go with E

1. Product of all the numbers is -1200. we can have lots of combination for negative and postive numbers

2. Memebers of the set = 6. We can have 5 negative, 1 postive or it can also have 1 negative and 5 postive or all postive or all negative

1&2

again lots of different possibilities eg-

S = -2,-2,-3,2,5,10
S = -2,2,2,3,5,10
S= -2,-2,-2,-3,-5,10
