Select the most appropriate option to substitute the highlighted segment in the given sentence.
Do you know where does she reside?

Correct option is C

The correct substitution of the highlighted words is (c) where she resides.
Explanation:
· In indirect questions (embedded questions), the word order follows a statement structure rather than a question structure. The auxiliary verb does is not used because the question is already introduced by Do you know.
· The correct sentence is: Do you know where she resides?
· Here, resides is correct because it agrees with the third-person singular subject ( she).
Grammatical rule used:
· In indirect questions, we do not use auxiliary verbs like does/did after where, what, why, etc. Instead, we follow the subject-verb-object structure.
Example: Incorrect: Can you tell me what does he want? Correct: Can you tell me what he wants?
Why other options are incorrect:
· (a) where does she resides?: Incorrect because does should not be used with the third-person singular form ( resides).
· (b) where she reside?: Incorrect because reside does not agree with the singular subject ( she).
· (d) where do she reside?: Incorrect because do is grammatically incorrect for the singular subject ( she).
