None of the 4. A vector in the opposite direction to 2i-4j+4k (magnitude 6) must be m(-2i+4j-4k) with m>0.

Square root of 736 is not even a rational number, let alone an integer.

take the negative of the og vector and make unit vector

then multiply that unit vector by

If i had to pick the most correct answer (that is only somewhat correct) I would say C. It does have modulus root(736) and each component (i,j,k) has been scaled into the opposite direction, even if they haven't all been scaled by the same factor.
