Option 1 -> (A), (B), (C), (D) - This sequence places excess demand after willingness to pay higher prices, which is illogical.
Option 2 -> (A), (C), (B), (D) - This follows the correct logical progression: definition of shift → excess demand → price adjustment → new equilibrium.
Option 3 -> (B), (A), (D), (C) - This places willingness to pay before defining the shift and puts excess demand at the end, which is incorrect.
Option 4 -> (C), (B), (D), (A) - This starts with excess demand before explaining what causes it, making it illogical.
Hence, Option 2: (A), (C), (B), (D) -> When demand shifts rightward: (A) First, it means quantity demanded is higher at every price; (C) This creates excess demand at the original equilibrium price; (B) The shortage causes consumers to bid up prices as they compete; (D) Finally, a new equilibrium is reached with both higher price and quantity. This sequence correctly captures the chain of events from cause to effect. -> correct
