What action does the word "renounce" imply?

The word "renounce" implies the action of giving up or resigning something, particularly in the context of formally declaring one’s abandonment of a belief, claim, or right. It suggests a deliberate decision to disassociate oneself from something that was previously held. For example, a person might renounce a title, an allegiance, or a belief they no longer support. This action emphasizes an active choice to sever ties with whatever is being renounced.

The other options do not accurately capture the essence of "renounce." Acquiring or accepting something new, supporting a belief, or complicating a situation represent actions that are fundamentally different and do not convey the same sense of relinquishment or abandonment inherent in renouncing.
