The correct answer is option (B):
pacification
The word CONTENTION signifies a state of disagreement or arguing, often involving conflict. We need to find an option that is the opposite or antonym of this meaning.
Let's look at the options:
* Argument: This is a synonym of contention, as both relate to a dispute or disagreement.
* Pacification: This word implies bringing peace, calming down, or resolving conflict. This is the opposite of contention.
* Debate: Similar to argument, debate also involves discussion and disagreement, therefore, a synonym.
* Quarrel: This indicates a heated argument or dispute, again similar to contention.
Therefore, the only option that directly contradicts the meaning of contention is pacification, indicating the act of establishing peace instead of disagreement.
