Answer:
B. Ismene views Antigone as reckless and is reluctant to assist Antigone. Antigone wants Ismene to agree to help her without first knowing the plan.
Explanation:
In this Sophocles's play, Antigone, the protagonist, wishes to give her brother a proper burial, although the king forbade it, declaring that anyone who disobeys this will be sentenced to death.
Antigone, despite of this law, can't let her brother unburied and his body dragged around by animals, while Ismene is too afraid to break the law. This represents the basic conflict between the two sisters.
In these lines, we see that Ismene feels Antigone is up to something and by calling her rush, she knows it will be something reckless and driven by emotions.
Antigone, however, wants her sister to help her in her mission, before she reveals it, because she knows that Ismene would never accept it if she knew the plan.
