Genetically modified and engineered organisms are that can produce the gene and the product of interest when modified. Escherichia coli is a transgenic organism.
A modified organism through the genetic and molecular pathway alteration is called a transgenic organism. Various techniques are employed to alter the genetic mechanism of the organism.
They are prepared by inserting a genetic fragment of interest from some other species by the method of recombination technology and genetic engineering.
The organism in which the insertion and the alteration are done to produce the product of interest are transgenic. Here E.coli get altered by the insertion of the human insulin-producing gene.
Therefore, option C. transgenic organism is correct.
