Answer

Brief Explanations:

When medical research shows that grapefruit juice can adversely affect the effectiveness of certain medications, consumers' tastes and preferences regarding grapefruit are likely to change, leading them to buy less. Higher income usually leads to more consumption of normal - goods, not less. A change in the number of sellers affects supply, not demand directly. And the price of oranges is a factor for the demand of oranges relative to grapefruit, not the main reason for the change in grapefruit demand here.

Answer:

B. people will buy less grapefruit because their tastes and preferences have changed.
