The answer as per NTA was option-4. Let us know if we've missed something.


Inferior good -> A good whose consumption decreases when income rises (negative income effect)

Giffen good -> A good whose consumption decreases when its price falls (upward sloping demand curve)

Giffen goods are a subset of inferior goods -> all Giffen goods are inferior, but not all inferior goods are Giffen goods.

ObservationWhat it tells us
Price falls, demand fallsDemand curve slopes upward -- this is the definition of a Giffen good
Income rises, consumption risesThis is the behavior of a normal good (positive income effect)

It cannot be answered correctly using standard NCERT theory because the two given conditions are mutually contradictory.

However, option-4 was awarded marks.
