Which of the following sentences uses an Article INCORRECTLY?

What is a time of your arrival?

The correct answer is Option (2) → What is a time of your arrival?

The error is the use of the indefinite article "a" before the word "time" in this specific context.

• When the word time is followed by a defining phrase (like "of your arrival"), it refers to a specific, unique moment. In such cases, the definite article "the" must be used.

• The speaker is asking for the specific time they will arrive.

Correction: What is the time of your arrival?
