According to Charles' Law, at constant pressure, the volume of an ideal gas is directly proportional to its absolute temperature.

V ∝ T

Or, V = kT (where k is a constant)

Now, if the absolute temperature triples (i.e., T --> 3T), then the volume (V) of the gas will also triple:

V' = k(3T) = 3(kT) = 3V

Therefore, the volume of the gas will change by a factor of 3.

Hence, the best choice is C) 3.
