Concept:An iconoclast is someone who rejects or attacks long-held beliefs, customs, and institutions.
Explanation:The word comes from Greek "eikon" (image) and "klastes" (breaker).
Originally, it referred to people who destroyed religious images.
In modern usage, it means a person who challenges or refuses to follow established beliefs and traditions.
Option A is too narrow because an iconoclast attacks more than just cultural icons.
Option B is incorrect because gaining attention is only a possible side effect, not the true meaning.
Option D is wrong because an iconoclast does not negate his own positions; he opposes society's accepted norms.
Option C precisely matches the definition: a person who does not adhere to accepted beliefs and traditions.
Answer:Option C — Person who does not adhere to accepted beliefs and traditions.
