Which one of the following attributes is NOT true for uniform circular motion?

The distance is always equal to the displacement

The correct answer is option 4. The distance is always equal to the displacement.

In uniform circular motion:

The speed of the body is constant

The velocity of the body keeps changing, because of change in direction

The direction of velocity is perpendicular to the radius of circle at any point.

Distance travelled keeps increasing

The magnitude of displacement oscillates between zero and half the circumference.

Clearly, distance is not equal to the displacement. When the object returns to its initial point, the displacement becomes zero, but distance is greater than zero.
