A

5 meters per second

B

10 feet

C

0.7 grams per centimeter cubed

D

3 blocks east

D. 3 blocks east

Explanation: Displacement refers to the distance covered in a specific direction. Therefore, it is a vector quantity with both magnitude and direction. From the choices given;

A. 5 meters per second; This is speed

B. 10 feet; This is distance since it has not specified the direction.

C. 0.7 grams per centimeter cubed: This represents density in g/cm³

D. 3 blocks east: This is displacement as it shows the distance to be covered in a specified direction.
