Worked Solution

Step 1: Air is a gas and can be compressed. Step [2-9]: Once the basketball is fully inflated, the outer material prevents it from expanding much more. Step [2-9]: Additional air will be compressed inside, so the volume of the ball remains almost constant while air pressure increases.

Correct answer: It will remain roughly the same.
