Correct option is B
The correct option to fill in the blank is (B) an.
Explanation:
The word “island” begins with a vowel sound (/aɪ/), so the article “an” is used before it for correct pronunciation and grammatical consistency.
Example: How did you like living on an island for six months?
Explain why other options are incorrect:
- A: Used before consonant sounds, not suitable here.
- No word required: Article is mandatory before singular countable noun.
- The: Used when the island is known/specified, which is not the case here.
Information Booster: Use “an” before vowel sounds (a, e, i, o, u) and “a” before consonant sounds regardless of spelling.
