Correct option is A
The correct option to fill in the blank is (A) a.
Explanation: The sentence talks about a general (non-specific) "little dog", so the indefinite article "a" is used.
Example: We found her playing with a little dog.
A (हिंदी अर्थ): एक (गैर-निर्दिष्ट वस्तु के लिए)
Meanings of the other options:
· B - An: Used before vowel sounds (एक - स्वर से शुरू होने वाले शब्दों के लिए)
· D - The: Refers to specific item (वह खास)
Information Booster: Use “a/an” for introducing something for the first time or non-specific objects.
