Final answer:
Typically, the school zone warning sign is a pentagon; however, given the options, the closest match is a rectangle, although it is not the typical shape for such a sign.
Explanation:
The school zone warning sign is typically a pentagon. This unique shape helps to distinguish it from other road signs. This question, however, does not list a pentagon as an option, so we assume it might be an oversight or a trick question. In the list provided, the closest match to a typical school zone sign would be the rectangle (option c), as traffic signs that are not warning signs are generally rectangular in the United States. It's important to remember that while diamonds are often used for road warnings, school zone warnings have a distinct shape not mentioned here.
