Which type of health insurance plan has contracts with selected physicians and specialists to provide medical services?
a. point-of-service (pos) plan
b. managed care
c. health maintenance organization (hmo)
d. preferred provider organization (ppo)

I would say HMO. The reason is it says SELECTED physicians. An HMO is an in network where you can only go to certain doctors and facilities. In return the doctors receive a little less than what they would originally be paid by other insurances. PPO's you can go to any doctor you want, however the insurance may not cover as much. Hope this helped. I would go with HMO.

What's the question again?
