Which of the following would indicate a relatively large amount of market power?

c. A highly inelastic demand._

A highly inelastic demand will provide a relatively large amount of market power. A highly inelastic demand represents a situation where a firms product sales are not affected by changes in prices but the demand remains constant irrespective of changes in price either upward or downwards. When demand of a commodity is inelastic, an increase in the price of the commodity will not lower its demand thus the firm will continue earning revenue through the season.
