Final answer:

Option A). The human heart beats 42 more times than the elephant's heart in one minute.

Step-by-step explanation:

The heart beats 288 times every 4 minutes, or 72 beats per minute if you divide 288 beats by 4 minutes. The heart rate of the elephant is 150 beats per minute for five minutes, or 150 beats / five minutes. The elephant's heart rate is subtracted from the human heart rate to get the difference: 72 beats per minute - 30 beats per minute = 42 beats per minute. Consequently, in a minute, the human heart beats 42 times more than the elephant's heart does.

Correct question:

A. 42 times
