Cost calculated per quintal is known as:

Correct option is C

The answer is (c) Cost of Production.

"Cost per quintal" means the cost associated with producing one quintal of a product, so "Cost of Production" is the most accurate term to describe this concept.

Why other options are incorrect:

(a) Cost of farming:

While "cost of farming" is related to the overall expenses involved in running a farm, it doesn't specifically refer to the cost per unit of output.

(b) Cost of cultivation:

"Cost of cultivation" is a narrower term than "cost of production" as it focuses solely on the costs directly related to growing the crop, excluding things like processing or marketing.

(d) Total cost:

"Total cost" refers to the sum of all costs incurred in producing a product, including both direct and indirect costs. Cost per quintal focuses on the unit cost, not the total cost.
