Explanation:

Certainly! Let's go through each option:

- Option 1: Along the Tangent

- Tangential acceleration occurs if the speed of the particle is changing.

- If the speed is constant, tangential acceleration is zero.

- Option 2: Along the Radius

- Centripetal acceleration acts along the radius.

- It points towards the center of the circle.

- This keeps the particle in its circular path.

- Option 3: Zero

- Acceleration is not zero if the particle is revolving.

- It must have centripetal acceleration to maintain circular motion.

- Option 4: Along the Circumference of the Circle

- Acceleration cannot act along the circumference.

- Movement is along the circumference, not acceleration.
