What is the signal used to request medical assistance?

• A. X
• B. N
• C. Y
• D. An Arrow

Answer: (A)

A clear, urgent signal for medical help must be instantly recognizable and unambiguous. The symbol X fits this need because it is visually distinctive and easy to reproduce as a quick gesture or sign. It stands out from ordinary signals and is understood as a call for assistance, prompting a rapid response from bystanders or responders. By contrast, a plain letter doesn’t inherently convey an emergency, and an arrow points to a direction rather than indicating a need for medical aid. So the X signal is the most effective choice for requesting medical assistance.
