Answer:
Three serving utensils
Step-by-step explanation:
A website is a collection of web pages. These web pages are created with web development tool like HTML, CSS, Javascript and other web tools. A web page is made of a header, a body and a footer.
The header contains introductory elements like a logo, main topic, menu or navigation bar etc.
The self service salad bar in the question is represented by a navigation bar. The navigation bar contains the salad bar menu which are "fresh greens mixture", "vegetable" with a dropdown menu of two vegetable types and "salad dressing" with a dropdown menu of four salad dressing types.
All these makes three menus or utensils in the salad navigation bar.
