Partisan is best defined as

• A. One-sided or partial
• B. Impartial
• C. Strongly prejudiced in favor of something
• D. Someone who is devoted to a political party

Answer: (C)

Partisan means having a strong bias in favor of a particular side, group, or cause. It signals more than just liking one side; it implies a readiness to support it and to judge evidence in its favor, often with little regard for opposing viewpoints. That’s why strongly prejudiced in favor of something is the best fit for the term. Being one-sided or partial is related but doesn’t emphasize the depth of bias as clearly. Impartial is the opposite, describing neutrality. Being devoted to a political party describes allegiance, but doesn’t automatically convey the biased judgment that “partisan” implies.
