问题如下：
Marion is considering purchasing medical insurance. He asks his investment manager for advice regarding a policy that potentially would allow him to go to essentially any medical service provider with a"reasonable and customary" fees. Given Marion’s policy preference, which type of medical insurance should his investment manager recommend?
选项：
A. Indemnity plan
B. Preferred provider plan
C. Health maintenance organization plan
解释：
A is correct.
考点：Health/Medical Insurance
解析：indemnity plan允许被保险人前往任何医疗服务机构，但被保险人必须支付一定比例的"合理"费用。
A third type of plan is a health maintenance organization (HMO), which allows office visits at no, or very little, cost to encourage individuals to seek help for small medical problems before they become more serious 这里的Office visit是病人到医院 还是医院到病人呀 该怎么理解呢
