Leghorn is an improved variety of chicken that originated in central Italy and is now used as layer chicken in many countries. These are good layers of white egg and used commercially and industrially to make highly productive egg-laying hybrids. There are ten color varieties of these hens recognized so far. These are mainly white, red, black-tailed red, light brown, dark brown, black, buff, etc.

Additional Information: Chick is one of the most common domestic fowl with a number larger than any other bird or domesticated fowl. They are a primary source of food for humans as their meat and egg are rich in proteins. They have multiple maternal origins in South Asia, Southeast Asia, and East Asia but the natural group found in most of the world originated in the Indian subcontinent.
These are generally omnivores and have distinguishable male and female characters. But these characteristics may change from breed to breed. In the whole world, more than 50 billion chickens are reared for their eggs and meat. The ones that are reared for meat are called broilers which are larger in size than the hens which are reared primarily for eggs.

Therefore, the correct answer is "Leghorn".
