Which of the following is a standard component of a sandwich wrap?

A tortilla is an essential component of a sandwich wrap because it serves as the outer layer that holds all the filling ingredients together. Wraps are characterized by their use of a flatbread, like a tortilla, which is typically made from wheat or corn. This allows for versatile fillings, which can include proteins, vegetables, sauces, and cheeses, making the wrap easy to eat while encapsulating a variety of flavors.

In contrast, a green salad, fresh fruit, and soup are not standard components of a sandwich wrap. While they may complement a meal that includes a wrap, they do not define what a wrap is. The tortilla specifically provides the structure needed to create the wrap, enabling it to be rolled up with various fillings, thus making it a key element of the dish.
