India's indigenous pigs generally give birth to young ones at a time?

Answer: (b) 4–6

Indigenous pigs usually have litters of about 4–6 — smaller than exotic breeds.

The idea

Local (desi) animals are bred by nature for toughness: they survive on poor feed and resist disease, but they produce less. Imported farm breeds are bred for output: more piglets, faster growth, and more care needed.

Desi pig: small, hardy, 4–6 piglets → Exotic breed such as Large White Yorkshire: large, 8–12 piglets → Cross-breeding: tries to combine the two

Why the others are wrong

(d) Exotic breeds like Large White Yorkshire can have 8–12.

The trap

Exotic farm breeds have big litters; desi pigs have small ones.

Also know

Pig rearing is most important in the North-East. African swine fever reached that region in 2020 and killed large numbers of pigs.
