Final answer:
The statement is correct. When a skydiver's parachute opens, the air resistance increases, while gravity remains the same.
Step-by-step explanation:
The statement is b) Correct.
When a skydiver's parachute opens, the air resistance increases, while gravity remains the same. Air resistance is a force that opposes the motion of an object moving through the air. As the parachute opens, it catches more air, creating more resistance, which slows down the descent of the skydiver. However, gravity continues to act on the skydiver, pulling them downwards.
