Which type of quantity has both magnitude and direction?

The correct choice is the one that defines a type of quantity that possesses both magnitude and direction. This specifically refers to vector quantities. For instance, when considering velocity, it has both a speed (the magnitude) as well as a stated direction (e.g., 60 km/h to the north).

In contrast, scalar quantities, such as mass and speed, only have magnitude and do not include any directional component. Mass simply indicates the amount of matter within an object, while speed indicates how fast an object is moving without specifying its travel direction. Therefore, the defining characteristic of a vector is its requirement to always be associated with a direction as well as a numerical value, making it distinct from scalar quantities.
