Context from the Passage: The third paragraph states: "...art increasingly faces the commodification of art. The aesthetic is repackaged as a spectacle for quick consumption, detached from complexity, nuance, and risk. The challenge, therefore, is to protect artistic integrity against market and media forces that may reduce it to banality."
Meaning of "Banality": The word "banality" (സാധാരണത്വം / തുച്ഛത) refers to the state of being completely ordinary, unoriginal, boring, or lacking in depth and fresh ideas.
Why (b) is correct: "Triviality" means the quality of being insignificant, shallow, or lacking importance and depth. The passage warns that commercial market forces strip art of its deep meaning and "complexity," reducing it to something shallow and meant only for quick consumption—which perfectly matches the concept of triviality.
