What does GMO stand for?

GMO stands for "Genetically Modified Organism." This term refers specifically to organisms whose genetic material has been altered using genetic engineering techniques. These modifications are made to achieve specific traits, such as increased resistance to pests or improved nutritional content. The correct choice precisely captures the widely accepted terminology used in scientific literature and discussions around biotechnology and agriculture.

While the other options present variations of the term, they do not accurately reflect the standard definition recognized by scientists and regulatory agencies. The term "genetically manipulated" implies a broader range of genetic alterations and is not the terminology commonly adopted in scientific contexts. "Generalized Modified Organism" and "Genetic Modification Option" do not correspond to any established terms in genetics, further underscoring why the chosen answer is the most accurate.
