Answer:
b. direct object
Explanation:
The whole noun clause "whichever guidelines they believed were followed by the majority" is the direct object of the transitive verb "violated" carried out by the subject "The nonconformists." There is no indirect object in the sentence, and no predicate nominative either, since there are no copulative verbs in it. The only preposition in the sentence is "by" and its object is not a clause.
