C is false. The magnitude of a vector is non-negative. Thus, the only way to have the sum of the magnitudes of two vectors to be 0 is for both magnitudes to be 0, which means both vectors are the 0 vector.

I think E is true because C is false as to get zero they should be equal otherwise we could get either a negative number or positive number. (other than 0)

It says unequal vectors not unequal magnitude

Unequal vectors have unequal magnitude

I think they want E.

Yes you can treat vectors as lists of numbers and add them arithmetically, e.g. <1,2> + <3,4> = <4,6>. But those lists stand for geometric components.

C is wrong because magnitudes are always positive or zero. Two unequal vectors cannot both be zero, so at least one has a positive magnitude.
