Explanation:

• In the recently-released Nature Index table 2020, India is placed twelfth globally in science research output. The top five positions have gone to the United States of America, China, Germany, United Kingdom and Japan. The Nature Index is a database of author affiliation information collated from research articles published in an independently selected group of 82 high-quality science journals.
• The database is compiled by Nature Research, a division of the international scientific publishing company Springer Nature that publishes academic journals.
• Globally the top-rated Indian institutions in this list are Council of Scientific and Industrial Research (CSIR), a group of 39 institutions at the 160th position and Indian Institute of Science (IISc) Bangalore at the 184th position. Hence all statements are correct.
