Hint: Exotic breeds are foreign species of dairy cattle used for crossbreeding with the indigenous breed of cattle. Crossbreeding is done to harness good traits of both of the lineages in their offsprings.

Complete answer:
Jersey is a British species of dairy cattle from Jersey. It comes under the Channel Island cattle breed along with Alderney (now extinct) and Guernsey. It is very productive and produces quantities of milk that are ten times their own weight per lactation. The milk is rich in butterfat and has a yellowish tinge to it. It is very much adaptive to a variety of climatic conditions and has a high heat tolerance.
Holstein-Friesian is a breed of dairy belonging to the Dutch provinces of North Holland and Friesland, and Schleswig-Holstein in Northern Germany. These animals are said to have the world’s highest productivity. It is highly widespread all over the world in more than 150 countries. They exhibit a piebald pattern of black and white or red and white.
Bos indicus is also referred to as zebu or indicine cattle or humped cattle. It is a domestic indigenous species of cattle originating from South Asia. They are tolerant of high temperatures and can be farmed throughout tropical countries. It is used as draught, dairy, beef cattle and they are also used for their byproducts like dung for fuel and manure.
Brown swiss: This breed of dairy cattle comes from America. It was selectively bred to obtain desirable qualities. It is ideal for cheesemaking because its ratio of protein to fat is suitable for it.

Therefore the answer is (C) Bos indicus.

Note:
 Ayrshire is also an exotic species from Scotland.
- The milk yielding capacity of buffaloes is three times more than cows.
- Gir, Sahiwal, Red Sindhi, Deoni are some of the indigenous species.
