Answer:
C, Paying money to farmers directly
Step-by-step explanation:
Deadweight loss is defined as a loss in the economic efficiency that occurs when the market equilibrium for a good or service is not met/acheived/attained.
It can also be called excess burden or inefficiency of allocations.
From the question, the smallest dead weight loss will be to pay money directly to farmers as this will try to create almost an equilibrium for the goods produced by the farmers. Paying money directly to farmers will also ensure that the prices of goods and services are agreeable and of benefit to both the farmers, consumers/buyers and the government as well.
Cheers.
