Answer:
C) field forces
Step-by-step explanation:
A) pushing forces (wrong option)
---> gravitational force: an invisible force that pulls objects towards the earth
---> electric force: a contact force that pushes or pulls objects without making any contact, making it a technically non-pushing force
B) contact forces (wrong option)
---> gravitational force: since it is an invisible force (as stated in the explanation for option A), it is a non-contact force
---> electric force: as stated in the explanation for option A, it is also a non-contact force
C) field forces (correct option)
---> gravitational force: is a type of force field since it is a non-contact force
---> electric force: is also a type of force field that cause the attraction or repulsion of forces without actual contact between the charges
D) applied forces (wrong option)
---> not applicable for both forces as supported by all the above information
