Correct Answer:
B. Horse-breeding
The correct answer is Horse-breeding. The Lower Chenab Colony was a significant agricultural and settlement project during the British Raj, designed to promote specific economic activities and land use. Common tenancy types included grants for Camel-owning (for transport and agriculture), Tree-planting (for forestry and environmental benefits), and allotments to Village headmen (Zaildars/Lambardars) for administrative and leadership roles. Horse-breeding, while an important activity, was not a distinct or primary category of tenancy specifically designated within the Lower Chenab Colony's land settlement schemes. The other options represent actual tenancy types.
