Answer:
D. magnitude
Explanation:
Scalars are quantities that are fully described by their magnitude (size) only. For example, a temperature is fully described by saying "80 degrees Celsius." We do not need to include a direction.
A vector contains both magnitude and direction. Acceleration is fully described by including both speed and direction: "45 m/s, North."
Both scalars and vectors have magnitude.
I think it’s A but I’m not sure
