If Person a Uses a Threat to Compel Person B

If person A uses a threat to compel person B to do something, does this commit the fallacy of appeal to force?

A) Yes, because person A is using force, rather than reasons, to control person B.
B) Yes, because person B is not doing the thing voluntarily.
C) No, because person A only used the threat of force, and not any real force.
D) No, because person A is compelling a behavior, not belief in the truth of a proposition.
E) It depends on whether or not this was a legitimate use of force.
