The goal of genetically engineering crops is to increase yield and profit.
The correct response is "to increase yield and profit." Genetically engineering crops aims to modify their genetic makeup to enhance their productivity and profitability. To find the correct answer, you can eliminate the other options that are not aligned with the objective of genetically engineering crops. In this case, options like making the product more expensive, reducing genetic diversity, and developing new pathogens are not valid goals of genetically engineering crops. By process of elimination, "to increase yield and profit" is the most suitable answer.
