Answer 2

Explanation:

Magnetic force and electrostatic forces are non-contact force as the force applied on an object without any contact with it, similarly, with gravitational force this is force applied without being aware of it and all time.

Muscular force can be applied only while in contact with the object. So, it is a contact force, not a non-contact force.
