Is always constant
Includes magnitude
Has direction
Depends on a reference frame

The correct answer to the question is it has direction .

Step-by-step explanation:

Before coming into any conclusion, first we have to understand a vector.

A vector is a physical quantity which not only requires magnitude but also direction for its complete specification. It is also in accordance with parallelogram law of vector addition.

The speed of a body is a scalar quantity. It has only magnitude . On the other hand, velocity is the speed in a given direction. Hence, it has magnitude as well as direction.

The speed of a body is simply distance travelled per unit time while velocity is the net displacement of a body per unit time. Since, time is relative and dependent on frame of reference, so both speed and velocity depend on frame of reference.

The area marked X lies in velocity region will contain the properties which are not in speed region.

Hence, the area marked X will denote simply that velocity has direction.
