Long before his death, Pablo Picasso had become one of the most important artists in history.
Correct answer
C
Rationale
The correct answer is C, 'Had become.' The sentence is referring to an action that occurred in the past before another past action, hence requiring the past perfect tense 'had become' instead of 'became.' This construction is used to indicate the sequence of events. In this case, it highlights that Picasso's importance as an artist was established before his death.
