Select the correct option:
Her rebuttal, though eloquent, failed to ______________ the central issue raised by the opposition.

Correct option is A

The correct option to fill in the blank is (a) address.
Address means to deal with, respond to, or speak directly about an issue/problem. (Hindi meaning: संबोधित करना/मुद्दे पर बात करना)
The sentence says her rebuttal was eloquent but did not deal with the main issue—so “failed to address the central issue” is the most precise and common usage.
Example: The report fails to address the root cause of unemployment.
Explain why other options are incorrect:
· (b) digress: means to go off-topic; you “digress from” a topic, not “digress the issue.”
· (c) circumvent: means to avoid or bypass cleverly; it changes meaning—she failed to address (deal with), not “failed to avoid.”
· (d) elude: means to escape or avoid capture/understanding; grammatically and contextually weaker here (the issue doesn’t “elude” someone in this structure).
Information booster:
· High-frequency collocations: address a problem/issue/concern/question.
