What does the expression - "Why waste oxygen on such utter nonsense?" mean in line 3 of the first paragraph?
A. Arguing on nonsense issues is nothing but wastage of energy
B. Medieval people do not like to waste their breath talking about a urinal
C. Medieval people had firm believe that an ordinary urinal cannot be art work; so they wouldn't waste their breath arguing on this
D. In medieval period there was solid authoritative definition of good, bad and aesthetics; so people wouldn't waste their time and energy making subjective arguments
Explanation: The question expects a general meaning of the expression, NOT in terms of medieval people. The general meaning is that arguing about something pointless is a waste of effort/energy (like oxygen/breath).
