Correct option is A
The correct option to fill in the blank is (A) Oxford Street.
Explanation: Street names don’t require an article. “Oxford Street” is a proper noun and doesn’t take “a”, “an” or “the” before it.
Example: I love shopping on Oxford Street whenever I visit London.
Why others are incorrect:
- B. the Oxford Street – Incorrect usage of "the" before street names.
- C. an Oxford Street – Not appropriate for proper nouns.
- D. a Oxford Street – Grammatically wrong; article "a" is not used with proper names.
Grammar Tip: Use no article before names of roads, streets, or parks unless a descriptive noun follows (e.g., the street called Oxford).
