Answer:
C. His opportunity cost of one watermelon is 2/3 of a cantaloupe.
Step-by-step explanation:
Opportunity cost refers to units of production sacrificed of one good to produce an extra unit of another good.
In the given case, for every 1 unit of Cantaloupe, a farmer is required to sacrifice the production of 1.5 units of watermelon.
This means, production of 1 cantaloupe = production of 1.5 water melons.
Thus, to produce an additional unit of watermelon, sacrifice of 1/1.5 cantaloupe is required.
This means, the farmer's opportunity cost of one watermelon in the form of cantaloupe sacrificed is 2/3 of a cantaloupe.
