Which description correctly defines transgenic (genetically modified) foods produced by recombinant DNA technology?

• A. Any food that has been cooked or processed in a factory, because industrial processing constitutes genetic modification under federal definitions.
• B. Foods produced only by classical cross‑pollination and selection over many generations without any laboratory manipulation of DNA sequences.
• C. Products derived from natural fermentation (e.g., yogurt) since microbial action automatically adds foreign genes to the ingredients during processing.
• D. Foods created by inserting specific genes from one organism into another using recombinant DNA methods to confer a new trait, distinct from traditional selection and crossbreeding.

Answer: (D)
