If due to technological improvement, supply increases, then:
(a) Only equilibrium price will fall
(b) Only equilibrium quantity will fall
(c) Only equilibrium price will rise
(d) Equilibrium price will fall and equilibrium quantity will rise

Dear Student, If due to technological improvement, supply increases, then Equilibrium price will fall and equilibrium quantity will rise. As, increase in Supply creates an excess supply at the initial price. Excess supply leads to the Equilibrium price to fall and quantity demanded to rise. Henceforth, option (d) is correct. Regards!
