EXPLANATIONPassive voice is commonly used to stress the verb and recipient of the verb rather than the subject.
Here are steps how to change an active voice to the passive voice :
~ passive forms are made up of the auxiliary BE with the past participle verb.
~ pay attention to the verb whether it's an intransitive or not. We can't change an intransitive verb to the passive voice.
~ pay attention to the verb tense used in the sentence.
~ the object of an active voice is moved to the subject of passive voice.
~ the subject of passive voice is moved to the object of passive voice by inserting the prepositition "by" to mention the doer of action.
BASED ON YOUR QUESTIONPAST PERFECT
A : S+had+verb3+Object
P : S+had+been+verb³+by+Agent
Subject (The old man)+Verb (had cut)+ Object (some trees near his shop).
changes to :
New Subject (Some trees near his shop)+Verb (had been cut)+ by+ Agent (the old man)
Hence, the correct answer is some trees near his shop had been cut by the old man (D).
