Correct option is C
We use ‘The’ (निश्चित/विशेष वस्तु के लिए) before unique objects (एकमात्र वस्तुएँ) like the Sun, Moon, Earth, Sky, etc.
- The Moon (चंद्रमा) is a unique heavenly body (एकमात्र खगोलीय पिंड), so the definite article ‘The’ is required.
- Also, personification is used here (“her face”), but the article rule remains the same.
Correct sentence: The Moon has hidden her face behind the cloud.
Why other options are incorrect:
- A (एक) – used before singular common nouns, not unique objects.
- An (एक) – used before vowel sounds, not applicable here.
- No Article Required (कोई article नहीं) – incorrect because Moon needs ‘The’
Hence, ‘The’ is the correct answer.
