The correct answer is (D).
The word “acquit” means to declare someone not guilty of a crime. In this case, the judge acquitted the prisoner from the charge of murder. This means that the judge found that the prisoner did not commit the crime of murder.
The other options are incorrect because they do not accurately reflect the meaning of the word “acquit.” Option (A), “of,” would mean that the judge found the prisoner guilty of murder but did not punish them. Option (B), “with,” would mean that the judge found the prisoner guilty of murder but gave them a light sentence. Option (C), “about,” would mean that the judge was not sure whether the prisoner was guilty of murder.
I hope this explanation is helpful. Please let me know if you have any other questions.
