The answer is
A) Manually
Explanation:
American Sign Language (ASL) is a complete and complex language that employs signs made by moving the hands combined with facial expressions and gestures of the body.
When done as casual, isolated signs, numbers "1 through 5" are typically produced palm-back by native Deaf adult signers. For example, if someone asks you how many brothers you have and you have "2" then you would reply by holding up the number 2 with the palm facing backward. However, the palm should be forward when doing a two-or-more-digit number such as "53," or a series of numbers such as a phone number, the time of day, ages, and if you are trying to emphasize a point.
