Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Experiments are being conducted on a new drug that could revolutionise the treatment of the disease by the research team.
In passive voice, the object of the action (experiments) becomes the subject.
The verb "is conducting" changes to "are being conducted."
The agent (the research team) can be placed at the end with "by".
The focus shifts from the research team to the experiments.
