The correct option is A Dolly
Dolly was a female domestic sheep, and the first animal to be cloned from an adult somatic cell, using the process of nuclear transfer. She was cloned by Ian Wilmut, Keith Campbell and colleagues at the Roslin institute, based near Edinburgh. She was born on 5 July, 1996 and died from a progressive lung disease 5 months before her seventh birthday. The cell used as the donor for the cloning of Dolly was taken from a mammary gland, and the production of a healthy clone therefore, proved that a cell taken from a specific part of the body could recreate a whole individual. Hence, option A is correct.
