What should she do with the wrench

An astronaut is a short distance away from her space station without a tether rope. She has a large wrench. What should she do with the wrench to move toward the space station?

a) Throw it directly away from the space station.
b) Throw it parallel to the direction of the station's orbit.
c) Throw it toward the station without letting go of it.
d) Throw it directly toward the space station.
e) Throw it opposite to the direction of the station's orbit.


Which one do you think and why? Please explain, thank you.

a) Throw it directly away from the space station.
The reaction will give the astronaut a small velocity towards the space station.
The astronaut and the space station are stationary with respect to each other, so that is all that is needed.
