Genetically modified food products have not become universally accepted because

Explanation

Genetically modified food products are foods that have been modified through genetic engineering to enhance certain desirable traits. The question asks why genetically modified food products are not universally accepted. Option A suggests that genetically modified food products are not tasty as others produced by conventional means. This option is incorrect because taste is not a major concern when it comes to genetically modified food products. In fact, some genetically modified food products, such as tomatoes, have been modified to have a better taste. Option B suggests that genetically modified food products are usually costlier than others produced by conventional means. While this may be true in some cases, it is not the main reason why genetically modified food products have not become universally accepted. Option C is the correct answer. It suggests that the effect of genetically modified food products on human consumers is not yet fully understood. This is a major concern for many people, as the long-term health effects of consuming genetically modified food products are not yet known. As a result, some people are hesitant to consume them. Option D suggests that the technology can be applied only in developed countries. This is not true, as genetically modified food products are grown and consumed in both developed and developing countries. In conclusion, genetically modified food products have not become universally accepted because their effect on human consumers is not yet fully understood.
