Select the correct option: Her rebuttal, although polished, did not __________ the core issue raised by the opposition.

The correct option is (a). The sentence means that even though her rebuttal sounded well-prepared, it did not deal with or speak directly to the main issue. The verb address means to deal with a problem, issue, or topic directly; to respond to it appropriately (Hindi meaning: समाधान करना/मुद्दे पर बात करना). Example: The minister promised to address the concerns of the farmers. Why other options are incorrect: Option B: depress – to make someone sad or reduce something (Hindi meaning: उदास करना/कम करना), which does not fit the context. Option C: illude – not a standard verb in this context; it is incorrect/rare and does not convey the required meaning (Hindi meaning: अमान्य/ अप्रचलित). Option D: circumvent – to avoid dealing with something directly (Hindi meaning: टालना/किनारा करना). The sentence says she did not do something; the needed word is the direct action she failed to do, i.e., address the issue. So the correct answer is (a)
