The correct answer is C) ad hominem.
Elizabeth Benedict wants to abolish the death penalty because she is a bleeding-heart liberal. The logical fallacy that the statement contains is ad hominem.
When in a discussion, the term ad hominem refers to the use of prejudices or feelings instead of arguments or intellect. Some people use it as a fallacious argumentative strategy on any circumstance of the subject in discussion, instead of focusing on the subject itself. The individual who uses ad hominem only attacks and does not presents arguments that support its opinions.
In this case, the logical fallacy that Benedict’s statement contains is ad hominem.
