Answer: C and D.
Explanations:
- A: velocity is a vector (has magnitude and direction).
- B: friction is a force, hence a vector.
- C: mass is a scalar (only magnitude).
- D: a bare "direction" gives no magnitude (it can be represented by a unit vector, but as stated it lacks magnitude), so it is not a full vector quantity.
