Answer 2

The answer is C. 100 meters west - vector.

A quantity is a vector quantity when it has both properties: magnitude and direction.
On the other hand, a quantity is a scalar quantity when it only has magnitude.
Since C. has magnitude (100 meters) and direction (west), then it is a vector quantity.
