Which of the following foods is a good source of protein?

The question inquires about which food is a good source of protein. Fish and chicken are both excellent sources of protein, as they provide essential amino acids necessary for various bodily functions, including muscle repair and growth, hormone production, and immune system support.

Fish, particularly certain varieties like salmon and tuna, not only offer a high protein content but also come with healthy omega-3 fatty acids, which are beneficial for heart health. Similarly, chicken is a lean meat that is widely recognized for its protein density, making it a staple in many diets focused on muscle building and weight management.

Considering that both fish and chicken are rich in protein, the best selection would be the option that includes both of these protein sources. Using just one of them, as indicated in the response to the question, does not capture the complete essence of the options provided. Therefore, the most accurate answer would emphasize the combination of both fish and chicken, as they collectively represent a good source of protein.
