1. A monopolist's profit maximisation model:

	a.	Can be solved using either the price or the quantity supplied as control variables, and both methods will produce identical numerical results.
	b.	Can only be solved using the quantity supplied as a control variable, and using the price as control variable would produce different numerical results that are not economically meaningful.
	c.	Is usually solved using the quantity supplied as a control variable, and using the price as control variable would produce different numerical results that are appropriate for describing markets in which the monopolist fixes the price rather than the quantity supplied.
	d.	None of the above.
