Brent is most likely in the bargaining stage of dying.
<h3><u>Explanation:</u></h3>
According to psychiatrist Elizabeth Kubler Ross, there are five stages of dying or grief written in her work On Death and Dying which is very helpful for doctors in dealing with such kinds of patients.
The five stages of dying are:-
<u>Denial:</u> In this stage, the patient enters a denial mode and denies the fact that his/her death is real.
<u>Anger:</u> In this stage, the patients may get angry about the fact that they are dying.
<u>Bargaining:</u> In this stage, the patient might try to bargain for their death from the doctors and God mostly in exchange for money or good deeds.
<u>Depression:</u> Here, the patient might get depressed upon realizing what they could and couldn't do.
<u>Acceptance:</u> Here, the patient completely accepts reality.
From observing the question, it is clear that Brent is in the Bargaining stage of dying as he is praying. Hence, option A is correct.
