Select the option that expresses the given sentence in direct voice.
The scientist told the students that light travels faster than sound.
Show answer & explanation
Correct answer: B
Explanation
The given sentence is in indirect speech ('The scientist told the students that...'). To convert this into direct speech, we need to report the exact words spoken by the scientist inside quotation marks.
When converting indirect to direct speech, 'told' is often changed back to 'said to'.
The tense inside the quotation marks should reflect the original spoken words. Since the statement 'light travels faster than sound' is a scientific truth, the simple present tense is retained.
Option B correctly follows these rules.
