Explanations:The question asks about the location of CSIR-NIIST, which stands for the Central Scientific Instruments Organisation - National Institute of Science Communication and Information Resources. This institution is a part of the Council of Scientific and Industrial Research (CSIR) and is known for its significant contributions to research and development, particularly in the field of alternative technologies.
CSIR-NIIST is located in Kerala, a state in southern India. The institute has been involved in various research projects, including the development of alternatives to single-use plastics. This is an important area of research due to the environmental concerns associated with plastic waste and the need for sustainable materials.
The correct answer is Kerala because the institute is situated in this state. The other options, Gujarat, Tamil Nadu, and Telangana, are incorrect as they do not host the CSIR-NIIST. These states are known for their own contributions to science and technology, but they are not the location of this specific research institution.
Understanding the location of research institutions like CSIR-NIIST is important for students preparing for competitive exams, as such questions often appear in general knowledge sections. It is also useful for those interested in the field of environmental technology and the development of sustainable materials.
