Answer

Answer:

C. Positive acceleration describes an increase in speed; negative acceleration describes a decrease in speed.

Brief Explanations:

Acceleration is the rate of change of velocity. Positive acceleration means velocity (speed in non - vector context here) is increasing, and negative acceleration (also called deceleration) means speed is decreasing.
