Final answer:
A photograph will be the best form of illustration to support the redesign of a restaurant's menu, providing customers with a clear and enticing visual representation of the dishes.
Step-by-step explanation:
A restaurant is redesigning their menu. Along with the text describing the dishes, which form of illustration would best fit the menu design? A photograph will be the best form of illustration to support the new menu of the restaurant. Photographs provide a clear, attractive, and realistic representation of food that can entice customers and give them an accurate idea of what to expect. In contrast, diagrams are more suited for presenting data or processes, sketches may appear too casual or unfinished for a professional menu, and graphs are generally used for numerical data representation. A well-taken photograph can showcase the dish's presentation, portion size, and ingredients, making it a powerful tool for menu design.
