Type of Mass
When we measure the mass using spring balance, we actually measure what type of mass?
About Gravitational Mass and Inertial Mass:
The two are quite independent of each other. There is no obvious reason why the two should be identical. However, they happen to be identical. Several sophisticated experiments have been performed to test this equivalence and none of them has supplied any evidence against it. The general theory of relativity is based on the principle of equivalence of inertial and gravitational mass.
But the question asked above has a specific answer. Therefore, think logically and click the valid option.

A spring scale/spring balance newton meter is a type of weighing scale.
It consists of spring fixed at one end with a hook to attach an object at the other. It works by Hooke’s Law,
which states that the force needed to extend a spring is proportional to the distance that spring
is extended from its rest position. Therefore, the scale markings on the spring balance are
equally spaced. A spring scale can not measure mass, only weight [wikipedia]
