Show answer & explanation
Correct answer: B
In a data interpretation table, finding the entity with the highest value for a given year means comparing the values listed in that year's column across all rows and picking the largest one.
From the table, the 2021 values are: Jio = 2135, Airtel = 2230, and Vodafone = 2080.
Comparing these three values: 2230 is greater than 2135, and 2135 is greater than 2080.
So the ordering from highest to lowest is Airtel (2230) > Jio (2135) > Vodafone (2080).
As an independent check, Airtel's value also grew the most from 2020 (1775) to 2021 (2230), consistent with it holding the largest 2021 figure among the three operators.
Therefore, Airtel had the highest number of customers in 2021.
