Which of the following is considered a type of appetizer?

A canape is considered a type of appetizer because it is a small, prepared, and often decorative food item served before a meal, typically as a finger food that can be eaten in one bite. Canapes are usually composed of a base, such as a cracker or bread, topped with various spreads or garnishes, engagingly showcasing flavors and textures. They are commonly served at social gatherings and establish a welcoming atmosphere prior to the main course.

The other options, while delicious, do not fit into the traditional definition of an appetizer. Brownies, for example, are sweet desserts typically enjoyed at the end of a meal. Pasta salad can be served as a side dish but is not generally classified as an appetizer in a formal dining context. Similarly, fruit tarts are dessert items, often served at the conclusion of a meal rather than as a precursor to the main courses.
