Choose the most appropriate option to complete the given sentence:-

After analysing data of last few decades, data scientists _____ to the conclusion that climate change is accelerating.

have come

The correct answer is Option (4) → have come

The correct tense here is the Present Perfect Tense (have come).

• The action (analysing data) and the resulting action (coming to a conclusion) occurred in the past ("After analysing data of last few decades").

• However, the result of this past action—the conclusion—is relevant and true in the present (the current understanding is that climate change is accelerating).

The Present Perfect Tense connects a past action to the present, making "have come" the best fit.
