Correct option is D
Option
(d) contains an error.
Explanation: The use of
"has been read through" is incorrect because it suggests a passive structure, whereas the subject "He" is performing the action.
· The correct form is:
"He has been reading through the archives..." or
"He has read through the archives..."
· "Read" is the verb here, and it should be used actively.
·
Grammatical rule used: Use active voice with present perfect or present perfect continuous when the subject is the doer of the action.
Example: She has been writing reports all day.

Information Booster: Avoid passive voice when the subject performs the action and the focus is on the process.
