The correct answer is:
C. Velocity incorporates the direction of an object, while speed does not account for it.
**Explanation:**
- Speed is a scalar quantity that measures how fast an object is moving irrespective of its direction. It is always a non-negative value.
- Velocity is a vector quantity that includes both the speed of the object and the direction in which it is moving. It can indeed be positive or negative depending on the chosen reference direction.
