Question

I'll call you .......................... I arrive at the airport.

• A. while
• B. since
• C. when
• D. during

Hint:

Use "when" to refer to a specific time in the future.

Answer 1

The Correct Option is C

Step 1: Understand the usage of conjunctions.
In this sentence, "when" is the correct conjunction to indicate the time something will happen. "When" is used to show the time of an event in the future.
Step 2: Analyze each option.
- (A) while: "While" suggests a simultaneous action, but it's not appropriate for this sentence.
- (B) since: "Since" is used to show a period of time from a specific past point, but it's not suitable for future events.
- (C) when: Correct. "When" correctly indicates the time the action will happen.
- (D) during: "During" refers to an ongoing period, which doesn’t fit here.
Step 3: Conclusion.
The correct conjunction to indicate time in this sentence is "when."
