This house is used very rarely by us.
A. We are using this house very rarely.
B. We use this house very rarely.
C. We used this house very rarely.
D. We uses this house very rarely.
Answer: Option B
Solution (By Examveda Team)
The given sentence is in the passive voice: "This house is used very rarely by us."To convert it to active voice, identify the subject, verb, and object:
Subject (doer): us (which becomes "we" in active voice)
Verb: is used (present simple passive)
Object (receiver): this house
The present simple passive ("is used") changes to the present simple active ("use") in the active voice.
So, "This house is used very rarely by us" becomes "We use this house very rarely."
Therefore, Option B is correct.

this is in past tense
