Earth's great inertia is the key factor leading to negligible effects on its motion in interactions with everyday objects, as per Newton's third law of motion. Here option B is correct.
Newton's third law of motion states that for every action, there is an equal and opposite reaction. In the context of interactions between Earth and everyday objects, it's important to consider the mass and inertia of Earth.
Inertia is the tendency of an object to resist changes in its state of motion, whether at rest or in motion. Earth, being an enormous and massive object, possesses immense inertia.
When everyday objects interact with Earth, they exert a force on Earth, and by Newton's third law, Earth exerts an equal and opposite reaction force on these objects. However, due to Earth's substantial inertia, the resulting motion or acceleration of Earth in response to these interactions is negligible. Here option B is correct.
