The Indian Space Research Organisation (ISRO) is collaborating with Raman Research Institute to construct the X-ray polarimeter. The satellite is scheduled for launch on January 1, 2024, at 9:10 AM, using a Polar Satellite Launch Vehicle (PSLV-C58). (Statement 1 is incorrect)
XPoSat, or X-ray Polarimeter Satellite, is India’s first polarimetry mission. The satellite’s primary goal is to measure the polarization of intense X-ray sources in the 8-30 keV energy band.
Apart from NASA’s Imaging X-ray Polarimetry Explorer (IXPE) which was launched in 2021, XPoSAT is the second polarimetry mission in the world.

(c) Both 1 and 2
Group of Friends will act as a platform to promote accountability for all acts of violence against the United Nations peacekeepers by facilitating support to the host state, creating awareness, exchanging information, sharing best practices, supporting initiatives, and mobilizing resources.
Bangladesh, Egypt, France, India, Morocco and Nepal have joined the group as co-chairs to promote accountability for crimes against peacekeepers.
Group of Friends represents the “political will” of member states, particularly of the troop and police contributing countries, to champion the implementation of the provisions of U.N. Security Council resolution 2589, which was adopted in August last year under India’s Presidency of the Council.

(a) Transparency International
India ranked 93 out of 180 countries in the 2023 Corruption Perceptions Index (CPI). The CPI is a scale from 100 (very clean) to 0 (highly corrupt). The 2022 CPI was published in January 2023 and ranks countries based on the situation between May 1, 2021 and April 30, 2022. Transparency International, a non-governmental organization based in Berlin, has published the CPI annually since 1995. The organization’s purpose is to combat global corruption and prevent criminal activities arising from corruption.

(c) Bacteria that can cause gastrointestinal infection
Salmonella is a bacteria that can cause serious illness, including salmonellosis, a gastrointestinal infection that causes fever. Salmonella can be found in the intestines of animals, including birds, and humans can contract it by eating foods contaminated with animal feces. These foods include chicken, beef, pork, eggs, fruits, vegetables, and processed foods.

Black holes are indeed cosmic objects with incredibly strong gravitational pull, so strong that not even light can escape their grasp. This point accurately reflects the established definition of black holes.
In April 2019, the Event Horizon Telescope (EHT) collaboration successfully captured the first-ever image of a black hole, specifically the Sagittarius A* located at the center of our Milky Way galaxy. This marked a significant milestone in astronomical observation and provided valuable insights into the nature of black holes.
While the concept of wormholes connecting different areas of spacetime is a fascinating subject in theoretical physics, there is no concrete evidence of their existence within black holes or elsewhere in the universe. This statement introduces a hypothetical concept not yet supported by conclusive observations or experiments (Statement 3 is incorrect).
