Answer: Option A
Solution (By Examveda Team)
He was refused admittance by the peon.Given sentence is in Past simple tense and it is in active voice, we need to change it into passive voice.
Rule :
Subject + (was / were) + V3 + Optional Agents.

Option C can only be the answer if it was in this form.
Admittance was refused to him by the peon.
By the peon should come in last as it is the subject.
I think option C can also be the answer of it.
