Which of the following statements are true?

(A) Milk obtained from ‘Rosie’ is nutritionally more balanced for human babies than natural human milk.
(B) Biopiracy refers to the use of bioresources without proper authorization from MNCs.
(C) GEAC is the decisive body for safety and validity of GMOs and GM research respectively.
(D) Transgenic animals help us to understand the contribution of genes in the development of disease.

Choose the correct answer from the options given below:

The correct answer is (C) and (D) only.

Let us analyze each statement step-by-step to understand why this option is correct:

Statement (A): "Milk obtained from ‘Rosie’ is nutritionally more balanced for human babies than natural human milk."
This statement is incorrect. Rosie was the first transgenic cow, produced in 1997. Her milk was enriched with human alpha-lactalbumin (containing 2.4 grams per liter) and was nutritionally more balanced for human babies than natural cow's milk, not natural human milk. Natural human breast milk remains the most ideal nourishment for human infants.

Statement (B): "Biopiracy refers to the use of bioresources without proper authorization from MNCs."
This statement is incorrect. Biopiracy refers to the unauthorized use of bioresources by multinational corporations (MNCs) and other organizations without proper authorization or compensation from the countries and people concerned (especially developing countries/indigenous communities who own these traditional resources).

Statement (C): "GEAC is the decisive body for safety and validity of GMOs and GM research respectively."
This statement is correct. GEAC stands for the Genetic Engineering Appraisal Committee. It is the official body in India under the Ministry of Environment, Forest and Climate Change that makes decisions regarding the validity of genetic modification (GM) research and the safety of introducing genetically modified organisms (GMOs) for public services.

Statement (D): "Transgenic animals help us to understand the contribution of genes in the development of disease."
This statement is correct. Many transgenic animals are specifically designed to serve as models for human diseases. They help researchers investigate how genes contribute to the development of diseases such as cancer, cystic fibrosis, rheumatoid arthritis, and Alzheimer's disease.

Therefore, only statements (C) and (D) are true, making (C) and (D) only the correct choice.
