Which of the following animals is commonly domesticated for meat production?

The primary reason for choosing the animal most commonly domesticated for meat production is based on agricultural practices. Chickens are among the most widely domesticated animals for meat production due to their rapid growth, high feed conversion efficiency, and the prevalence of poultry farming worldwide. This makes them a staple in many diets and a significant source of protein.

While camels can be domesticated and used for meat, milk, and as pack animals, they are less common in this specific role compared to chickens. Elephants and giraffes are not typically domesticated for meat production; they serve different roles within their ecosystems and cultures, but not as common sources of meat in agricultural or livestock settings.

Thus, the commonality and efficiency of chickens in meat production clearly place them above the other options, illustrating their significance in food systems globally.
