Select the most appropriate option to fill in blank [C].
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. “the.”
The sentence reads: “They learned about the importance of mountain ranges like the Himalayas.”
When referring to a specific mountain range, English convention uses the definite article “the”—as in “the Himalayas,” “the Alps,” etc.
This is because names of mountain ranges are treated as plural proper nouns that typically take 'the.'
Why the other options are incorrect:
No article (option 1) is incorrect here—omitting “the” before “Himalayas” would sound unnatural and is not standard usage.
“An” and “a” (options 3 and 4) are indefinite articles, appropriate for singular count nouns, not for established, plural mountain ranges.
