Jenny Has Carried Out a Reaction in Her Lab to Equilibrium

Jenny has carried out a reaction in her lab to equilibrium. She tells her friend, Joe, that there are no longer any reactions occurring in the solution. Joe tells her she is wrong, because:

A) A reaction at equilibrium has no reactants left.
B) A reaction at equilibrium has reactions occurring, just at equal forward and backward rates.
C) The reaction is still occurring, just moving forward a little slower than before.
D) The reaction is not occurring anymore, but still can occur if you shake the solution.
E) Joe is wrong as well, and none of the above answers is correct.
