Answer: A) The attic was the site of the crime.
Step-by-step explanation: homophones are words (two or more) that have the same or similar pronunciation, but different meanings, spellings of functions. In the given sentences the homophones are: site, cite, and sight. Site is a place, or a short of "website", cite is a synonym of quote, and sight is vision or something that we can see. In the sentences, the correct one is option A. Option B should be "The thief stood there in plain sight." Option C should be: "I was sure to include a list of the sources I cited in my essay" and the last one should be "Javier really enjoyed visiting the website."
