The correct option is D Generated by introducing foreign DNA into a cell and regenerating a plant from that cell
The plants obtained through genetic engineering contain a gene/genes usually from an unrelated organism, such genes are called transgenes and the plants containing transgenes are called as transgenis plants. These plants are often called as genetically modified or GM crops, e.g. Flavr saur tomatoes, golden rice. Plants are made transgenic for identification, expressing the gene activity in time, to produce several chemicals like fatty acids, sugars, cellulose, rubber, etc.
So, the correct option is option C.
