Correct Answer: perfectly inelastic

Solution : The correct answer is perfectly inelastic .

The value of the next best alternative use of the component of production is referred to as the opportunity cost. When a factor of production's supply is perfectly inelastic, the quantity provided does not fluctuate in response to price fluctuations. This signifies that the factor of production is limited and difficult to replace.
