Final answer:
In the military, the number of aiguillettes worn on each shoulder depends on rank. Higher-ranking officers may wear two or three aiguillettes on each shoulder while lower-ranking officers wear one.
Step-by-step explanation:
In the military, aiguillettes are ornamental cords worn on the shoulder as a symbol of rank or affiliation. The number of aiguillettes that may be worn on each shoulder depends on the rank of the individual. Typically, one aiguillette is worn on the right shoulder, but higher-ranking officers may wear two or three aiguillettes on each shoulder.
For example, in the United States Army, aiguillettes are worn by general officers on both shoulders. They wear two aiguillettes on each shoulder during military ceremonies. Non-general officers, such as colonels and majors, may wear a single aiguillette on the right shoulder to symbolize their rank.
Therefore, the correct answer is b) Two aiguillettes may be worn on each shoulder.
