Option 1: Rs. 40 per kg -> At equilibrium, quantity demanded equals quantity supplied (qᵈ = qˢ). Setting 200 - p = 120 + p, we get 200 - 120 = 2p, which gives 80 = 2p, so p = 40. At this price, both qᵈ and qˢ equal 160 units, confirming market equilibrium where there is no shortage or surplus. -> correct
