Final answer:
Reverend Parris in The Crucible is an antagonist because he is instrumental in the initiation of the witch trials, endangering innocent lives due to his concerns over reputation, and because he is portrayed as greedy and generally disliked in the town.
Step-by-step explanation:
Reverend Parris is considered antagonist in The Crucible largely due to his role in promulgating the hysteria of the witch trials in Salem. Parris contributes to the tragic events and the endangerment of innocent lives. He initiates the witch trials because he is concerned about his reputation and position in the community more than the truth or the well-being of others. His actions put innocent lives in danger, as he supports the trials and allows himself to be swayed by the panic and fear in the town. This aligns with option B from the provided choices, as he gets the witch trials started.
Additionally, Reverend Parris is depicted as a greedy and disliked character in Salem, aligning with option D. His concern for his own wealth and standing among the townspeople overshadows any moral duty he has to his congregation or family.
