Solution

The correct option is C $V \propto T$
Charles' law states that "at constant pressure, the volume of a given mass of a gas, increases or decreases by $\frac{1}{273.15} t h$ of its volume at $0^{\circ} C$ for every rise or fall of one degree in temperature".
So $V \propto T$
Hence, the correct option is $C$ .
