I don't understand how they get B) as an answer.

1)The product of any two numbers in the list is equal to 0

so the list could look like 0x0x0x0x0x0x0 or it could look like 2x0x2x0x2x0x2
so obviously 1)is out

2)The sum any two numbers in the list is equal to 0.

so the list could look like 0+0+0+0+0+0+ or -3+3+(-3)+3+(-3)+3

I know i must be doing something wrong...would anyone like to clarify this for me....thanks

your reason for saying 1) is not sufficient is good.

for 2), ANY two numbers added together have to equal 0, but if you had your list of -3+3+(-3)+3+(-3)+3, you could add -3 and -3 and get -6... alternately, you could do 3+3 and get 6.
therefore, all the numbers have to be 0. thus, two is sufficient.

let me know if that makes sense.
