Select the most appropriate synonym of the underlined word in the following sentence.

Dr. Brahm Prakash advised me to take care of the performance degraders and cautioned me against seeking optimal performance from the participating work centres.

best

The correct answer is option 4. best.

The most appropriate synonym for "optimal" in the sentence is Best

Optimal means the best or most favorable conditions or results.

Best directly translates to the desired meaning of achieving the absolute peak performance.

Minimum refers to the smallest or least amount, which is the opposite of what Dr. Brahm Prakash is advising.

Faulty implies something is broken or malfunctioning, not necessarily related to performance level.

Worst indicates the absolute lowest performance, again the opposite of what's intended.

Dr. Brahm Prakash is suggesting focusing on fixing issues that hinder performance (performance degraders) rather than striving for the absolute best performance from the work centers. "Best" captures the idea of aiming for a high level of performance without necessarily needing the ideal or maximum output.
