Select the option that will improve the highlighted part of the given sentence. In case no improvement is needed, select 'No improvement required'.
Do I need finish this work today itself?

Correct option is B

The correct substitution of the highlighted words is (b) Need I.
Explanation:
The sentence uses a question structure but “Do I need finish” is incorrect because “need” as a modal verb does not take “do/does” in interrogative structure when used as a modal auxiliary.
Correct: Need I finish this work today itself?
Grammatical Rule:
· When “need” is used as a modal verb (showing necessity), it does not require do/does/did.
· Structure: Need + subject + base verb + object?
Example:
· ❌ Do I need speak now?
· ✅ Need I speak now?
�� Info Booster:
“Need” can be both a main verb and a modal verb.
· As a main verb: I do not need help.
· As a modal: Need I go now?
Why other options are incorrect:
• (a) – “Must I to” is incorrect (modal “must” not followed by “to”)
• (c) – Original sentence has incorrect modal usage.
• (d) – “Do I must” is grammatically invalid.
