Correct option is C
Only II (A price floor) is an example of an agricultural price support program. A price floor sets a minimum price for agricultural goods, ensuring that farmers receive a fair income even when market prices fall below the production cost. Governments use price floors to stabilize agricultural markets and protect farmers from price volatility.
Explanation of other options:
(a) Only III (Equilibrium pricing): Equilibrium pricing occurs naturally in free markets when supply equals demand, but it is not a price support mechanism.
(b) Only I (A price ceiling): A price ceiling sets a maximum price, typically used to protect consumers from high prices, not to support farmers.
Important Point: Price floors in agriculture, like minimum support prices (MSP) in India, ensure farmers’ welfare and market stability.
