From the words or group of words lettered A to D, choose the word or group of words that best completes each of the following sentences.
The committee has submitted its report………..the students’ riot
The correct answer is: D
Explanation
"The committee has submitted its report on the students' riot."
When presenting information that discusses a certain topic, then you are presenting information "on" that topic. "About" can also be used but it is less formal and not as precise as "on" If you make use of "about", you might not be suggesting that the central topic in the research is the "students' riot" but, there is a little bit of information about it in the report. This is why D. on is the correct answer.
