Correct Answer: Gravitation
Solution : The correct option is gravitation .
It is believed that gravity is an "action-at-a-distance" force. A force that acts on an item is known as an action-at-a-distance force since there is no visible physical contact between the object and the force's source. One well-known example of an action-at-a-distance force is gravity, as defined by Isaac Newton's law of universal gravitation.
