An Acrobat is a person who performs spectacular and daring gymnastic feats, such as tightrope walking, tumbling, or trapeze acts, often in a circus or athletic competition. The term implies a high level of physical balance, agility, and coordination. To clarify why the other options are incorrect: an Addict is someone who is physically or mentally dependent on a particular substance or activity; an Adonis is a term used to describe an extremely handsome young man (derived from Greek mythology); and an Advocate is a person who publicly supports or recommends a particular cause, policy, or individual. Thus, "Acrobat" is the only term that specifically describes a performer of physical, gymnastic stunts.
