He goes to ________ prison every week to visit his brother who works there as a security guard.

Answer: C. the

Answer: C) the
Explanation: Usually, institutional nouns like prison, school, hospital, church, bed take no article when visited for their primary purpose (e.g., "He went to prison" means he is a prisoner). However, if you visit the building for a secondary purpose—like a visitor or a contractor—you must use the definite article "the".
