The correct answer is
a decrease in the radius and an increase in the tangential speed
In fact, the centripetal acceleration of the satellite is given by:
where v is the tangential speed and r is the radius. We see that the larger the tangential speed, the greater the acceleration, and the smaller the radius, the greater the acceleration. Therefore, we see that we can obtain the greatest increase in acceleration if we increase the tangential speed and we decrease the radius.
