IPMAT 2023 - Verbal Ability Question 16

The phrase "go the extra mile" is an idiomatic expression that means to make a special effort or go beyond what is expected. In the context of the sentence, it suggests that these brands are making an additional effort to accommodate people with prosthetic legs by tailoring their pants in a way that makes it easier for them to put them on. Options (b), (c), and (d) do not convey the same idiomatic meaning and are not commonly used expressions. Therefore, option (a) is the most appropriate choice.
