force is a quantity that is measured using the standard metric unit known as the

a. m/s
b. meter
c. newton
d. joule

Newton is the unit of the force in standard metric.  

Option: C

Explanation:

The physical quantity which has both direction and magnitude is force. Force is also known as to be a pull or push of an object with respect to its mass that is responsible for the change in velocity (acceleration). To give motion for an object from one place to another force is to be applied on an object.

So, Force= mass x acceleration = kg x = Newton (N)

Symbolically Newton is represented as N.
