Which of these is a traditional Mexican dish?

A taco is a traditional Mexican dish consisting of a small hand-sized corn or wheat tortilla topped with a filling. The tortilla is then folded around the filling and eaten by hand. A taco can be made with a variety of fillings, including beef, pork, chicken, seafood, beans, vegetables, and cheese, allowing for great versatility and variety. They are often garnished with various condiments, such as salsa, guacamole, or sour cream, and vegetables, such as lettuce, onion, tomatoes, and chiles. Tacos are a common form of antojitos, or Mexican street food, which have spread around the world.

The taco predates the arrival of the Spanish in Mexico. There is anthropological evidence that the indigenous people living in the lake region of the Valley of Mexico traditionally ate tacos filled with small fish.

In the United States, National Taco Day is celebrated annually on October 4.
