• C. speed; acceleration
• D. velocity; acceleration

Answer 1

Answer: (A), (C)

The correct options are
A

In a uniform circular motion, speed remains constant.
But as the direction changes at every point, velocity keeps on changing.
In a uniform circular motion, the direction of acceleration keeps on changing as it is always directed towards the center.
