Solution

The correct option is A Dolly
Dolly the sheep was the first mammal to be cloned from an adult somatic cell in 1997. Hence she was not a GMO.

Bt brinjal was developed by introducing the cry gene in brinjal to protect it against brinjal fruit and shoot borers.

3 genes important for biosynthesis pathway of beta-carotene was introduced in rice to produce golden rice. Beta-carotene is a precursor of vitamin A and hence golden rice is fortified with vitamin A.

Tracy is a transgenic sheep. Gene for the production of human protein alpha 1-antitrypsin was introduced in her. The lack of this protein causes emphysema.
