The definition of a vector is a quantity of magnitude and direction and a scalar has magnitude but not direction. A is the correct choice because it says vector and has a magnitude of 100 and a direction of west. B is wrong because it is labeled as a vector with magnitude 76 but no direction. C is wrong because it is labeled as a vector with magnitude 15 but no direction. D is wrong because it has magnitude 1 and direction south but is labeled as a scalar instead of a vector. Respond with any further questions.
