The door is opened by him.

[hatgray]

Is it correct to say,

"The door is opened by him"

For example
Ben: Who opens the door everyday?
Amy: The door is opened by him.

Thanks.

It's grammatical, but a more natural answer is 'Mustapha' or 'The guy with the bunch of keys'.

 

[hatgray]

I cannot find the word "Mustapha" anywhere.
Is that a word in a dictionary?

 

[Rover_KE]

No — it's the name of the guy who does it whose name I plucked out of thin air. I might also have chosen 'Donald', 'Ali', 'Pedro', 'Imran' etc.

The question should be Who opens the door every day?

 

[ambitious-girl]

but a more natural answer is 'Mustapha'

It is an Arabic name, but it is a very common name given to boys in Iran. It is also spelled as "Mostapha" in Iran.

Is it correct to say,

"The door is opened by him"

For example
Ben: Who opens the door everyday?
Amy: The door is opened by him.

It is not natural because the question is about the person who opens the door, not the door, so the active sounds much better than the passive:

Bill. (short answer)
Bill opens the door.

or
Bill does.
