Answer: B

A transgenic crop is a genetically modified organism (GMO). Transgenic indicates that a transfer of genes has occurred using recombinant DNA technology. Generally a transgenic crop contains one or more genes that have been inserted artificially either from an unrelated plant or from different species altogether.

Budding and grafting in fruit plants does not include genetic editing or modification.
