The correct answer is: a) Native and Exotic breeds.
Crossbred cattle are a result of breeding between two different breeds of cattle. In Kerala, crossbred cattle are often bred between native breeds such as the Vechur and Ongole, and exotic breeds such as the Holstein-Friesian and Jersey. Crossbreeding can improve the productivity of cattle, such as by increasing milk production or beef yield.
Zebu and buffalo breeds are not considered to be crossbred cattle, as they are two different species of cattle. Domestic and wild cattle are also not considered to be crossbred cattle, as they are not different breeds of the same species.
