The change is taking place on the graph due to decrease in the demand curve, that moves the equilibrium points to downward.
Why demand decreases?
- The change in demand is also called the shift in demand curve, it changes due to change in other factors than own price of a commodity.
- In the given case, demand decreases due to change in the other factors than own price of a commodity on the same supply curve, but the supply curve moves also towards its left as the demand decreases.
- As a result, demand curve shift to its left and the equilibrium point also moves towards its left on the same supply curve.
Therefore, the option [B] is correct.
