Option 1 -> Price floor is the opposite of price ceiling; it sets a minimum price.
Option 2 -> Random price fixation is not a standard economic term.
Option 3 -> Maximum price fixation sets an upper limit on prices, which is exactly what a price ceiling does.
Option 4 -> Minimum Support price is another term for price floor, not ceiling.
Hence, Option 3: Maximum price fixation -> A price ceiling is a government-imposed maximum price that can be charged for a good or service. It is set below the equilibrium price to make goods more affordable for consumers. Since it establishes the highest price allowed, it is also known as maximum price fixation. Common examples include rent controls and price caps on essential commodities during emergencies. -> correct
