Answer:
Answer is B. counting the number of heartbeats for 6 seconds.
Step-by-step explanation:
To quote the text, "You must make a fist with one hand before using the index and middle fingers of your other hand to press down on the artery to find it. Once you have found the artery, locate your pulse and count how many heartbeats you can feel for 10 seconds. Multiply the number by 6 to get the approximate number of heartbeats in 60 seconds, or bpm."
