The correct answer is option c, that is, Tourette's syndrome.

Explanation:

Tourette's syndrome refers to an issue with the nervous system in which the individual possesses no control over his movements like turning his or her head, creating certain sounds like grunts. These activities are known as tics, and the person suffering from the condition loses the tendency to control their movements.  

An individual suffering from this condition blurt out words, and in place of saying anything blinks their eyes. Thus, in the given question, Orlando is suffering from this condition.
