When Mary usually quaffs three glasses of Lost Horizons Cabernet Sauvignon every day, her demand for her favorite vintage will be least probable affected by: (i) The plague of grape worms ruining the bouquet of Lost Horizons Cabernet (ii) Receiving a $2 an hour pay hike. (iii) The high price cut for Cloudy Head Cabernet, an identical wine. (iv) Lost Horizons buying the other vineyard, permitting production to double.
Can someone please help me in finding out the accurate answer from the above options.
