Genetically modified (GM) foods make it possible to produce more food on less land. However,
these foods are controversial. Which of the following is a valid concern about GM plants?
a. GM plants could transfer plant diseases to humans.
b. Corporations are now able to patent naturally occurring genes.
Chemical residues will enter the food supply without anyone knowing.
d. The high cost of GM seeds may force small farmers out of business.

Modified crops have been patented and marketed by private companies. The seeds produced have been sold to many small farmers with the promise of improved yields and hardy crop. However, the high cost of repurchasing seeds may often be prohibitive to small farmers hoping to keep their businesses afloat.

Further Explanation:

Genetically modified species (GMs) have their DNA altered or improved through genetic engineering methods usually GMOs include modifications in DNA through the incorporation of genes from all creatures such as plants, fungi, viruses and animals. These are referred to as transgenic organisms, which lead to several developments by increasing global food security which is the supply of food for the entire population.

GM crops are believed to be more robust in nutritional value and taste, immune to adverse weather conditions such as droughts. These can be resistant to pests, and should reduce the use of herbicides and pesticides
