Librarian: "Basing Restrictions on Loaning Books to Library Patrons on the Books

Multiple Choice

Librarian: "Basing restrictions on loaning books to library patrons on the books' content is absurd. The library is a place of learning and free access to information. If we place restrictions on that access, no matter how well intentioned, the result is to stifle education."
Concerned parent: "But many parents agree that reading books containing vulgarities is offensive and we do not want our children exposed to such language."
The concerned parent's rebuttal is flawed because it:

A) Attacks the librarian's character and not her argument.
B) Uses hyperbolic and inflammatory language in order to distract from the issue at hand.
C) Makes a generalization from one anecdotal situation.
D) Uses reasoning that does not respond to the librarian's main point.
E) Uses an ad hominem attack instead of responding to the argument.
