A) Animals like bulls for farm work as they have super power
B) Transgenic mice for testing safety of polio vaccine before use in humans
C) Transgenic models for studying new treatments for certain cardiac diseases
D) Transgenic Cow-Rosie which produces high fat milk for making ghee
Explanation
[Solution from source] NCERT states that transgenic mice are used to test the safety of vaccines, specifically polio vaccine, before they are used in humans. Rosie's milk was enriched with human alpha-lactalbumin protein, not fat. The disease models NCERT lists are cancer, cystic fibrosis, rheumatoid arthritis and Alzheimer's, not cardiac disease.
