ANSWER is option 1 i.e. instanceThe sentence refers to a particular art form, 'instance' refers to an example of something. An 'incident' refers to an example as well, but it can also refer to a 'violent and disruptive occurrence', thus this cannot be the answer. An 'accident' refers to an UNFORTUNATE EVENT that occurs unexpectedly. The sentence refers a SINGULAR occurrence, thus 'events' - which is plural - cannot be the answer. Thus, the correct answer is option 1.
