The industry that comes closest to perfect competition is

A) clothing.
B) the airlines.
C) wheat-growing.
D) steel.
E) the railroads.

Wheat-growing is often seen as an example of perfect competition because there are many small producers, a standardized product, easy entry and exit from the market, and access to information about prices and production techniques. Other industries, such as airlines and steel, have fewer players and may have more barriers to entry, making them less likely to exhibit perfect competition.
