Answer: e. Groucho will lose on a defense of bona fide occupational qualification because he will not be able to establish that only non-pregnant employees can perform as servers.
Step-by-step explanation:
Groucho would be unable to prove that a pregnant person will be unable to fulfil their occupational obligations because it is not uncommon to see pregnant women working. He will not be able to prove that that only non-pregnant workers can serve because his main reason of children asking embarrassing questions will not stand as children in this day and age are already knowledgeable of what it means to be pregnant and if they don't it will be an excellent opportunity to introduce them.
Customers will probably not object to pregnant women serving them as this is a natural phenomenon. The Federal Government also recognizes that Pregnant women can still work and for this reason amended Title VII accordingly.
