Little Legislative Debate and Congressional Guidance Exists on the Proper

Little legislative debate and Congressional guidance exists on the proper interpretation of Title VII's prohibition of sex discrimination because:

A) the majority of the members of congress were confident that the meaning of the terminology was self-evident and that any attempt to explain it would lead to confusion.
B) virtually all members of congress, at that time, were men and, therefore, did not understand the concept of sex discrimination well enough to explain it.
C) most members of congress, at that time, were men who felt that the discussion of sexual matters in a public forum was unseemly and inappropriate for a legislative body.
D) a southern legislator and civil rights foe inserted the prohibition of sex discrimination in a last-minute amendment to the Civil Rights Act of 1964, in an attempt to bring about the bill's defeat.
