Can a Coherent Argument Assert a Disjunctive Proposition, and Then

Multiple Choice

Can a coherent argument assert a disjunctive proposition, and then deny all of its disjuncts?

A) Yes, if each of the disjuncts could be denied, then they could all be denied.
B) Yes, because a disjunctive proposition does not assert that its disjuncts are true.
C) Yes, because the conclusion might be some combination of the disjuncts, rather than any particular one of them.
D) No, because whenever there is a disjunctive premise, there must be another premise that affirms at least one of the disjuncts.
E) No, because the disjunctive proposition asserts that at least one of the disjuncts is true.
