Consider the following statements regarding India-based Neutrino Obse...
The correct answer is option 'C', i.e., statements 1 and 3 only are correct.

1. A Mini-Iron Calorimeter (mini-ICAL) detector has been set up in Tamil Nadu:
The first statement is correct. The India-based Neutrino Observatory (INO) is a proposed underground research facility to study neutrinos. It is being set up in the Bodi West Hills region of Theni District in Tamil Nadu. The main component of the INO is the Mini-ICAL detector, which is a massive iron calorimeter.

2. This detector will detect both muons and neutrinos, mainly owing to the presence of cosmic ray background:
The second statement is incorrect. The Mini-ICAL detector primarily aims to detect atmospheric neutrinos, not muons. Neutrinos are elementary particles that are electrically neutral and have a very small mass. They interact very weakly with matter, making them difficult to detect. However, when neutrinos interact with the matter in the Mini-ICAL detector, they produce other charged particles, such as muons. These muons are the secondary particles that can be detected by the Mini-ICAL detector.

The presence of cosmic ray background is not the main reason for detecting neutrinos in the Mini-ICAL detector. Cosmic rays are high-energy particles, mainly protons, that originate from outer space. They continuously bombard the Earth's atmosphere, creating a background of particles, including muons. However, neutrinos are unique because they can pass through the Earth and most other matter without being significantly absorbed or deflected. Therefore, detecting neutrinos can provide valuable information about astrophysical phenomena and the properties of neutrinos themselves.

3. Mini-ICAL detector has layers of glass Resistive Plate Chamber (RPC):
The third statement is correct. The Mini-ICAL detector consists of layers of glass Resistive Plate Chambers (RPCs). RPCs are detectors made of parallel metal electrodes separated by insulating material. When a charged particle passes through the RPC, it ionizes the gas inside the chamber, creating a signal that can be detected and measured. These RPCs are used to detect the secondary particles produced by neutrino interactions in the Mini-ICAL detector.

In summary, the correct statements regarding the India-based Neutrino Observatory (INO) and the Mini-ICAL detector are:

1. A Mini-ICAL detector has been set up in Tamil Nadu.
3. Mini-ICAL detector has layers of glass Resistive Plate Chamber (RPC).

Therefore, the correct answer is option 'C'.
