The correct option is "1 and 3 only". The National Biodiversity Authority (NBA) plays a crucial role in safeguarding India's agricultural biodiversity by regulating access to biological resources and ensuring that the rights of local communities and indigenous populations over their genetic resources are protected, thus addressing biopiracy. Statement 3 is correct as the NBA's approval is necessary for applications related to Intellectual Property Rights (IPR) concerning biological resources, ensuring compliance with the Biological Diversity Act of 2002. However, statement 2 is incorrect because the NBA does not directly monitor scientific research on genetic modification; that responsibility lies with other regulatory bodies such as the Genetic Engineering Appraisal Committee (GEAC).
