beef The essential amino acids are those amino acids that the body can not synthesize, so they need to be included in the diet. Of the 4 foods presented as choices, 3 of them are from plants. It's possible to get all the essential amino acids from plants only, but that requires you to eat a wide variety of different plant proteins. In fact, a major concern for vegetarian is to insure that they get a wide enough variety of plant proteins so that they get all the essential amino acids. However, animal protein tends to have all the essential amino acids. Since the only animal based food in the list of choices is beef, that's the one choice that's most likely to contain all the essential amino acids.
