Explanation:

Here’s what you need to know:

- Chopal is a well-known town in Shimla district, but it isn’t the place with the government sheep breeding farm.

- Kiari is another location in the region, mostly recognized for its apple orchards—no sheep farm here.

- Jeori () is actually the spot where the Government Sheep Breeding Farm is established. It’s quite important for improving local breeds and supporting the wool industry.

- Mandal is a less prominent name when it comes to sheep breeding farms.

So, the answer is Jeori.
