Which word best completes the sentence: I will check ______ with you by the end of the week?

• A. In
• B. On
• C. With
• D. By

Answer: (A)

The main idea is using the phrasal verb check in with someone to mean touch base and provide an update. Filling in with in forms the common expression check in with you, which clearly signals you’ll reach out and report progress by the deadline. Using in makes the sentence natural and precise in a professional context. Other options don’t fit: check on with you isn’t a standard expression; check with you would suggest consulting or confirming something rather than giving an update by a deadline, and none of the other choices fit the intended meaning with this verb phrase.
