Answer: counterattack
Explanation:
When Jade's colleague pointed out to her that she was running late for a meeting, Jade responded, "Well, unlike you, I don't have much free time. I am up to my neck buried in work!" Jade is using counterattack as a defensive reaction.
Applied to this situation, a counterattack reaction would be oriented to stop an attack or what a person may consider a personal attack and give it back at them.
