Solution

The correct option is C the compartment of astronaut is kept on the periphery of rotating wheel like satellite.
On a rotating body, as we move away from center of rotation the centrifugal force increases. So, the centrifugal force is maximum at the periphery of a rotating wheel. Thus, having the astronaut room there would solve some of the weightlessness problem in satellite.
