Question

Fill in the blank with the most appropriate option:
__________ will Halley's Comet appear next? (time) [Basic]

• A. Which
• B. When
• C. Where
• D. What

Answer 1

The correct option is B When

The correct answer is Option B.

From the given options we have to choose the word that is used when one wishes to know the time of the occurrence of an event.

Option A-WHICH is used for asking particular information from a definite set.

Option C-WHERE is used for asking about a place or position.

Option D-WHAT is used for asking specific information.

None of the above words can be used to ask for the time of an event's occurrence.

Hence these options are not the correct answer.

Option B-WHEN is used when one asks about the time of the occurrence of an event.

Hence Option B is the correct answer.
