The first sentence tells us that the subject's brother has always been healthy. Thus, it can be concluded that the answer must be a place a healthy person does not require to visit.
Option A is correct. A hospital is a place where an unhealthy person is treated. Since the subject's brother is always healthy, he does not need to visit the hospital.
Option B is incorrect. A church is a place of worship and can be visited by a healthy person and thus, it is incorrect.
Option C is incorrect. A school is a place where people study. A healthy person is required to go to school and thus, school is incorrect.
Option D is incorrect. A garden can be visited by anyone regardless of their health. Thus, option D is also incorrect.
