Answer:
.A.The volume of a gas varies directly with its temperature at constant pressure.
Step-by-step explanation:
This law is expressed mathematically as;
Vâ /Tâ =Vâ/Tâ where
Vâ=initial volume
Tâ=initial absolute temperature
Vâ=final volume
Tâ=final absolute temperature
The temperature is converted to Kelvin when doing calculations where;
0°c = 273 K
An application of this law in real world examples could be  when a ball is left outside overnight it the cold, the ball shrinks a little in its volume due to decreased temperatures.

A is the answer for sure i got it right after working it out.
