Correct answer
Explanation
Ankylophobia is the abnormal and persistent fear of immobility of a joint. The term comes from 'ankylosis' (stiffening or fusion of a joint). This is different from Anthropophobia (fear of people) or anger-related phobias. Medical professionals use this term when describing joint-related anxiety.
