What is represented by a school zone sign?

Answer: B — School zone.

A school zone sign specifically indicates the presence of a designated area around a school where additional caution is required. This sign typically alerts drivers to reduce speed and be particularly vigilant for children who may be crossing the street or walking nearby during school hours. The purpose of such signage is to enhance safety for students, as they may be entering or exiting the school premises. While other choices may be relevant to areas where children could be present, they do not capture the specific intent of a school zone sign, which is focused on protecting students and young pedestrians in the vicinity of schools.
