Answer:
C.
Step-by-step explanation:
American Sign Language (ASL) is a sign language for Deaf communities in the US and some other parts of the nation.
In ASL, the months are signed by placing the non-dominant hand's index finger facing right and moving the dominant hand's index finger downwards. The months' names are signed by spelling the first three letters of the month with more than five letters. The exception is for September's name, which spells out with the first four letters.
Therefore, option C is correct.
