Physics

The object that experiences uniform circular motion is the car traveling around a roundabout at a constant speed.

The car is moving in a circular path (the roundabout) and its speed remains the same throughout the motion. The direction of the car's velocity is constantly changing as it moves around the roundabout, but the speed is constant, which is the characteristic of uniform circular motion.

Option A, A car speeding up as it turns left

A car speeding up as it turns left is not in uniform circular motion. In uniform circular motion, the speed of the object must be constant. Here, the car is speeding up, which means its speed is changing.
