Newton`s laws of motion are fundamental principles in physics that describe the relationship between the motion of an object and the forces acting upon it. However, these laws do not hold good for objects moving with velocities comparable to the velocity of light.

Option 1: Objects at rest. Newton`s laws are indeed applicable to objects at rest. The first law states that an object at rest will remain at rest unless acted upon by an external force.

Option 2: Objects moving slowly. Newton`s laws are applicable to objects moving at any velocity, including slow velocities. The second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Option 3: Objects moving with high velocity. Newton`s laws are applicable to objects moving at high velocities. However, when an object approaches the speed of light, relativistic effects become significant, and Newton`s laws are no longer accurate.

Option 4: Moving with velocity comparable to the velocity of light. This is the correct answer. When objects move at speeds approaching the speed of light, they exhibit behaviors predicted by Einstein`s theory of relativity rather than by Newton`s laws. Relativistic effects, such as time dilation and length contraction, become significant at such velocities.
