Correct option is B
The correct option to fill in the blank is (b) the; a.
Explanation:
The definite article 'the' is used before the names of specific forests (e.g., The Gir Forest). The indefinite article 'a' is used before 'beautiful deer' as it is a non-specific singular countable noun modified by an adjective starting with a consonant sound.
Example: We went to the Himalayas and saw a rare leopard.
Information Booster:
'The' is used for geographical features like forests, oceans, and mountain ranges. 'A/An' is used for general items mentioned for the first time.
So the correct answer is (b)
