The correct answer is: b) National Remote Sensing Centre
The National Remote Sensing Centre (NRSC) is an Indian government organization under the Department of Space (DOS) that is responsible for remote sensing activities in India. It was established in 1975 as the Space Applications Centre (SAC) and was renamed NRSC in 1981.
NRSC plays a vital role in mapping flood-prone areas in Assam. It does this by using remote sensing data to identify areas that are at risk of flooding. This data is then used to develop flood management plans and to warn people about potential floods.
The other options are incorrect because:
- Survey of India is a government organization that is responsible for surveying and mapping India. It does not play a vital role in mapping flood-prone areas in Assam.
- Geological Survey of India is a government organization that is responsible for geological surveys in India. It does not play a vital role in mapping flood-prone areas in Assam.
- Central Water Commission is a government organization that is responsible for water resources management in India. It does not play a vital role in mapping flood-prone areas in Assam.
