In a study, it was observed that the height of a person is proportional to the square root of his age up to the age of 25 years. The increase in height is then directly proportional to the age in excess of 25 years till a maximum age of 50 years, and then the height remains constant thereafter. If a 16-year old boy is found to have a height of 4 feet and a 50-year old man has a height of 6 feet, what is the expected height of a 45-year old man?

A5.2 feet
B5.5 feet
C5.7 feet
D5.8 feet
E5.9 feet
