Answer 1

The correct option is C

1, 2 and 4

Non-contact forces are those which do not require physical contact with the body to impart an effect. Among the given options, gravitational force, electrostatic force and magnetic force do not require physical contact with the body as in when the Earth attracts the moon or magnets attracting iron fillings. However in contradiction, muscular force requires direct physical contact to deliver the desired impact.
