Your firm's contract to sell office supplies to the federal government requires that you hire only subcontractors who agree not to discriminate,and include a nondiscrimination clause in their contracts with you.You've done a thorough investigation of the firms out there who could fulfill your needs for particular office supplies,and there is one who is significantly less expensive than all of the others.However,that firm has a well-known reputation for discriminating against Muslims.Your profit margin is already quite small for this project,and you worry about making any money at all.Which of the following is/are acceptable option(s) ,and why?

A) hire the firm that's cheaper, even though they discriminate, because they'll agree to put the clause in their contract, and that's all you need; besides, you can't afford to lose the government business
B) don't hire the firm that's cheaper, because it would disqualify your firm from the government contract if the government found out
C) talk to the firm that's cheaper, and try to persuade them to actually comply with a non-discrimination standard; then monitor the situation to ensure that they do, because its in both your interests
D) negotiate with other, non-discriminating suppliers on their prices to see if you can match the price of the discriminating supplier
