Answer:
Is aware that her tactics are not appropriate.
Explanation:
When Petrocelli states that the person must have lied, O'Brien objects to the statement. The most likely reason for the objection is that O'Brien believes Petrocelli does not have enough evidence to reach this conclusion. The fact that Petrocelli withdraws her question shows that she is probably aware that the tactic she just used is not appropriate.
