Concept:Subsidies are government supports that lower the cost of farming.
Explanation:Farmers receive subsidies so they can buy inputs like seeds, fertilisers, and agrochemicals at lower prices.
In practice, the government pays part of the cost to suppliers, allowing farmers to pay a reduced price.
This directly matches the option A.
Option B refers to infrastructure, which is a government service but not a subsidy in this form.
Option C mentions high tariffs, which increase input costs and harm farmers.
Option D is about loans, which are borrowed money and not a subsidy.
Thus, the correct form of subsidy is a reduction in the price of farm inputs.
Answer:A. reduced prices of inputs
