The National Biodiversity Authority (NBA) was established in 2003 to implement India's Biological Diversity Act (2002).The NBA is a statutory and autonomous body and it performs facilitative, regulatory and advisory functions for the Government of India on issues of conservation, sustainable use of biological resources and fair and equitable sharing of benefits arising out of the use of biological resources.

The National Biodiversity Authority (NBA) plays a crucial role in protecting Indian agriculture by checking biopiracy and protecting indigenous and traditional genetic resources.

While the NBA does have a regulatory role, it does not directly monitor and supervise scientific research on genetic modification of crop plants. This task is typically handled by other scientific and regulatory bodies.

Any application for Intellectual Property Rights related to genetic or biological resources cannot be made without the approval of the NBA. This is a significant measure to prevent the exploitation of India's rich biodiversity without proper compensation and benefit sharing.

Therefore, only statements 1 and 3 are correct.
