What error in reasoning is made in this argument?

a) The president uses a faulty attack pointing out ho the previous committee lacked organization
b) the president uses a band wagon appeal saying everyone is already on board with changing higher fees for the dance.
c) the president uses all-or-nothing thinking stating that people won't enjoy dancing if a different band is hired.

b) the president uses a bandwagon appeal saying everyone is already on board with changing higher fees for the dance.

This is an error in reasoning because just because a large number of people support something does not necessarily mean it is the best course of action. It doesn't address the actual arguments or reasons for increasing fees.
