Fill in the blank in the following sentence by choosing the correct option out of the ones that follow each sentence.
I would have helped you if you ________ me.

Correct option is C

The correct option to fill in the blank is (c) had asked.
Detailed Explanation (English):
• The main clause “would have helped” is a Third Conditional structure.
• Third Conditional talks about an unreal situation in the past (something that did not happen).
• In Third Conditional:
– If-clause uses Past Perfect (had + V³)
– Main clause uses would have + V³
• Therefore, “if you had asked me” is correct.
Correct sentence: I would have helped you if you had asked me.
Grammatical Rule Used (English):
• Third Conditional: If + had + V³, would have + V³
• Used for unreal past conditions and their unreal past results.
Grammatical Rule Used (Hindi):
• Third Conditional का प्रयोग उन स्थितियों के लिए होता है जो भूतकाल में हुई ही नहीं।
• संरचना: If + had + V³, और मुख्य वाक्य: would have + V³।
• इसलिए “if you had asked” सही है।
Example: If she had studied, she would have passed.
Why other options are incorrect:
• (a) asked: Simple Past, not matching “would have helped” structure
• (b) ask: Present tense, incorrect
• (d) have asked: Present Perfect, incorrect in if-clause of third conditional
