B
Step-by-step explanation:
Entreats is a very special kind of word. It is quite subtle. I think it is beyond a suggestion, but suggestion is part of its meaning.
Beg is a little bit too strong, but I think it is the intended answer, especially in this quotation. Certainly it is not a plea to abandon a murder, but that too is a possible answer.
I think the best thing to do is pick beg. Jocasta does not have the power to command. She can only tell Odysseus he should not do what he is doing.
