Understand that a rightward shift in the demand curve means an increase in demand at every price level.
Recall that for a normal good, demand increases when consumer income increases, causing the demand curve to shift rightward.
Analyze each option: a decrease in population size would reduce demand, shifting the curve leftward, so it cannot cause a rightward shift.
A decrease in the price of the good itself causes movement along the demand curve, not a shift of the curve.
A decrease in the price of a substitute good would typically decrease demand for the normal good, shifting its demand curve leftward.
