If we apply Newton’s First Law to torque then the statement will...
Newton's First Law for Rotation: an object at rest tends to remain at rest, and an object that is spinning tends to spin with a constant angular velocity, unless it is acted on by a nonzero net torque or there is a change in the way the object's mass is distributed.

Explanation:
Newtons's First Law of Motion states that an object will remain at rest or move in a straight line with a constant velocity, unless acted upon by an external force. This law can be generalized to rotational motion by considering the concept of torque.
What is torque?
Torque is the rotational equivalent of force. It is the measure of the ability of a force to rotate an object around an axis. Mathematically, torque is defined as the product of the force applied and the perpendicular distance from the axis of rotation to the point of application of the force.
Net torque and angular acceleration:
When a net torque is applied to a rigid object, it causes the object to experience angular acceleration. The angular acceleration is directly proportional to the magnitude of the net torque and inversely proportional to the moment of inertia of the object. The equation that relates torque, moment of inertia, and angular acceleration is given by:
τ = Iα
where τ is the net torque, I is the moment of inertia, and α is the angular acceleration.
Zero net torque and constant angular velocity:
If the net torque acting on a rigid object is zero, there is no angular acceleration. According to Newton's First Law, the object will continue to rotate with a constant angular velocity. This means that the object will maintain its rotational motion without any change in speed or direction.
Non-zero net torque and non-uniform angular velocity:
If the net torque acting on a rigid object is non-zero, it will experience angular acceleration. This means that the object's angular velocity will change over time. The rate of change of angular velocity depends on the magnitude of the net torque and the moment of inertia of the object. Therefore, the object will rotate with a non-uniform angular velocity.
Conclusion:
In summary, if the net torque acting on a rigid object is zero, it will rotate with a constant angular velocity. On the other hand, if the net torque is non-zero, the object will rotate with a non-uniform angular velocity. Therefore, the correct answer is option 'C'.
