Ferris wheel, Prankster Paul gets out of his
chair and climbs along the spoke of the wheel

unchanged.
B. decreases while his angular speed remains
unchanged.

Answer:

B. decreases while his angular speed remains  unchanged.

Explanation:

His angular speed will always be the same as the wheel's angular speed, which remains constant as it's in uniform motion. As for linear speed, which is defined as the product of angular speed and distance r to the center of rotation, and his distance to center is decreasing, his linear speed must be decreasing as well.
