A) The block at the left lands first.
B) The block at the right lands first.
C) Both blocks land at the same time.

The block at the right lands first. This is because it has a larger radius of rotation, which means it has a greater linear velocity and takes longer to complete one full rotation. Therefore, it will travel a greater distance and land first.
