Answer:
B.
Step-by-step explanation:
When standing up straight, the top of your crutches should be about 1-2 inches below your armpits.
The handgrips of the crutches should be even with the top of your hip line.
Your elbows should be slightly bent when you hold the handgrips.
To avoid damage to the nerves and blood vessels in your armpits, your weight should rest on your hands, not on the underarm supports.
