Answer: (A)

Verified step by step guidance

1. Understand that a rightward shift in the demand curve means an increase in demand at every price level.
2. Recall that for a normal good, an increase in consumer income leads to an increase in demand, shifting the demand curve to the right.
3. Recognize that a decrease in the price of good j itself causes a movement along the demand curve, not a shift of the curve.
4. Note that a decrease in consumer population reduces the number of buyers, which would shift the demand curve to the left, not right.
5. Understand that a decrease in the price of a substitute good makes the substitute more attractive, which typically decreases demand for good j, shifting its demand curve to the left.
