Answer:
Option (D) is correct.
Step-by-step explanation:
If we assume that beef is a normal good.
We know that there is a positive relationship between the income of the consumer and the demand for normal good. This means that if there is an increase in the income of a consumer then as a result the quantity demanded for a normal good also increases.
In our case, if there is an increase in the income level of the consumer then as a result the quantity demanded for beef also increases.
