Which of the following is a synonym for 'consummate'?

The word 'consummate' means to be extremely skilled or to exhibit a high level of proficiency in a particular area. This term often conveys a sense of mastery and excellence, suggesting that the individual in question has not only learned but has also perfected their skills to a high degree. Thus, 'extremely skilled' is the accurate synonym as it embodies the essence of the word 'consummate' perfectly.

The other options do not convey this same meaning. For instance, 'inexperienced' implies a lack of skill or knowledge, 'basic' suggests simplicity or fundamental skills rather than mastery, and 'average' indicates a level of performance that is neither exceptional nor poor. These words contrast sharply with the connotation of expertise that 'consummate' represents. Therefore, 'extremely skilled' aligns with the definition and usage of 'consummate' within a context of exceptional ability.
