 A. Gallus and white leg horn
 B. Desi variety with exotic bird
 C. Australorp male and white leghorn female
 D. None of the above

Answer 1

Hint: Austra white is a hybrid vigour of chicken which produces eggs throughout the year.

Complete answer:
Gallus is a common domesticated chicken, which is a subspecies of Gallus gallus known as the red jungle fowl. They are reared widely for meat and egg.
White leghorn is a breed of chicken which is used as layer chicken, which means raising egg laying poultry for commercial egg production. They are fighty in nature.
Desi variety of chicken refers to Indian varieties of chicken. They have plenty of flesh, but have poor egg laying capacity and are slow in growth. Ghagus, Brahma are some examples of these.
Exotic breeds are the improved breeds imported to this country and bred and acclimated to the local conditions. Australorp is an exotic variety, which is of English class and Australian origin and now very common in India. They are a good all round breed and mostly black in colour. They are developed as a utility breed with a focus on egg laying. And they are calm in nature.
Austra white is a cross of Australorp male and White leghorn female, which are two good egg laying varieties. They were developed in the early 1900s. Austra whites are excellent layers which produce more than 250, large, cream colour eggs per year and also raised as meat birds because they reach heavyweight. They are also known for their calm and tame nature, which they inherited from Australorp

Hence, the correct answer is option (C)

Note: 1. Austra whites are mostly white in colour, with black flecks.
2. Austra white is not a true breed, mating a male and female Austra white doesn’t produce Austra white offspring.
