A true statement about mass is that:
(a.) mass is often measured with a spring scale
(b.) mass is expressed in pounds
(c.) as the force of Earth's gravity on an object increases, the object's mass increases
(d.) mass is determined by comparing the mass of an object with a set of standard masses that are part of a balance

Based on newton's law of gravitation "every particle of matter in the universe attracts every other particle with a force that is directly proportional to the product of the masses of the particles and inversely proportional to the square of the distance between them".

It is mathematically expressed as:

F = [tex]\frac{Gm_{1} m_{2} }{r^{2} }[/tex]

F is the gravitational force on either particle

m₁ and m₂ are the masses

r is the distance between particles

G is the universal gravitation constant.

From this expression, we see that the force of earth's gravity is directly proportional to mass.

The statement that is true about Mass is:

(C) as the force of Earth's gravity on an object increases, the object's mass increases

Mass:

It is a measure of the object's inertial property, or the amount of matter it contains.

According to Newton's law:

Any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them. It states that as the force of Earth's gravity on an object increases, the object's mass increases.

Thus, correct option is C.
