Final answer:
Decius convinces Caesar to go to the Senate House by interpreting a dream as a positive omen and by suggesting that not going would make him seem cowardly and superstitious.
The correct option is B.
Step-by-step explanation:
The two reasons Decius gives for why Caesar should go to the Senate House are B) To avoid appearing cowardly and superstitious.
Decius cleverly persuades Caesar by reinterpreting Calpurnia’s dream, originally taken as an ill omen, as a favorable sign that signifies Caesar’s vitality and the Senate’s desire to offer him a crown.
Additionally, he appeals to Caesar's pride and fear of judgment by suggesting that the Senate might change their minds about honoring him if he does not appear, and that people would think he was afraid, which would damage his reputation as a fearless leader.
The correct option is B.
