Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The centrifugal force in the rocket frame of reference balances the gravitational force acting on the astronaut and hence, normal reaction on the astronaut is zero. Hence, an astronaut feels weightlessness in a satellite.

He feels a zero normal reaction because both the satellite and astronaut are under free fall. Hence, both assertion and reason and correct, and reason is the correct explanation for the assertion.
