As a child, Theodore Roosevelt suffered from asthma,

 so he set out on improving his fitness and ended up

  A                 B                    C

recovering fully of the illness by the time he

                 D

reached adulthood. No error 

                     E

The correct answer is D

Explanation: The error in this sentence occurs at D, where the preposition “of” does not agree idiomatically with the verb “recovering.” To correct this error, one could change “of” to the idiomatically correct “from.”
