Without the specific rate of recovery for Trisha's heart rate post-exercise, we cannot accurately determine her pulse rate 2 minutes after stopping exercise. The correct answer would require additional context or a description of her recovery curve.
Considering that Trisha's pulse rate is 78 beats per minute immediately after exercising, to determine what her pulse rate would be 2 minutes after stopping, we need additional information such as the rate at which her pulse decreases after exercise. Since this information is not provided, we cannot calculate the exact pulse rate.
However, if we consider general post-exercise physiology, it is likely that her heart rate would begin to fall as her body moves towards a resting state. A typical recovery rate can be around 15-25 beats per minute, so her pulse rate may decrease to somewhere in the range of 53-63 beats per minute after 2 minutes, if it were elevated due to exercise.
Without specific data to indicate Trisha's rate of heart rate recovery post-exercise, any of the provided options A) 76 bpm, B) 72 bpm, C) 80 bpm, and D) 74 bpm could be possible, but are purely speculative. Therefore, it's not possible to provide a precise answer to the heart rate question without adequate context or additional data regarding Trisha's heart rate decline curve immediately after exercise.
