[Pregnancy Peril] Julia, a Server at Café Sunshine, Found Out

[Pregnancy Peril] Julia, a server at Café Sunshine, found out she was pregnant. She was aware that Billy, her employer, had allowed employees who were ill for reasons unrelated to work to take paid time off. For example, Raul, another server, was off with pay for two months after suffering a mild heart attack, and Audrey, a cook, was off work for three months when she ran her personal watercraft into a dock and broke her leg. Julia, therefore, happily told Billy about her pregnancy. He angrily replied that as set forth in the employee handbook, pregnancy was completely voluntary; that she was not entitled to a dime when she was off work; and that she would be lucky if he even allowed her to continue working at all because she would not be as cute when she gained weight. According to Billy, being slender was a bona fide occupational qualification for all servers. He said that because the restaurant serves families, he was concerned that kids would ask embarrassing questions of their parents regarding Julia's condition. Julia was angry and threatened to sue. Billy told her, however, that he had taken a business law class back in 1980 and learned that discrimination based on pregnancy is not covered by Title VII.
-Is Billy's comment correct that pregnancy-based discrimination is not covered by Title VII?

A) He is correct, and pregnancy-based discrimination is not prohibited by federal law.
B) He is correct, and pregnancy-based discrimination is not prohibited by Title VII; but it is prohibited by Title IV.
C) Whether he is correct depends on the number of employees he has. Title VII was amended in 1989 to include pregnancy within its protection, but only for employers with over 50 employees.
D) He is incorrect because Title VII was amended in 1987 to include pregnancy within its protection.
E) He is incorrect because Title VII was amended in 1997 to include pregnancy within its protection for all employees other than professional level employees.
