Understanding the Task

The question asks for the most appropriate antonym of the word implied by the context. The sentence describes a situation where only one proposal was accepted, and the others experienced the opposite outcome.

Contextual Analysis

The sentence structure is: "Only one of his proposals was accepted in the meeting, while others were ________."

• The word 'accepted' means approved or agreed to.
• We need a word that means the opposite of 'accepted' to fill the blank, describing what happened to the *other* proposals.

Evaluating the Options

• 1. fulfilled: This means carried out or satisfied. It is not the direct opposite of 'accepted'. A proposal can be accepted but not fulfilled, or vice-versa in different contexts.
• 2. rejected: This means dismissed or refused to accept. This is the direct antonym of 'accepted'.
• 3. attended: This word relates to presence, usually at events, and is irrelevant to proposals being approved or disapproved.
• 4. agreed: This word often implies acceptance or concurrence, making it a synonym or closely related word to 'accepted', not an antonym.

Conclusion

The most appropriate antonym for 'accepted' in this context is 'rejected'. Therefore, the sentence should read: "Only one of his proposals was accepted in the meeting, while others were rejected."
