The correct answer is option (C):
RQSP
The correct answer is RQSP. Here's the breakdown:
The goal is to create a coherent and meaningful sentence or short passage. We need to look for a logical flow, often starting with the subject or the main idea.
* R: "India plans to offer an astronomical site at Hanle..." This seems like a good starting point as it introduces the location and the general plan.
* Q: "...in Leh for an international collaboration that is..." This builds upon R by specifying the location (Leh, which is a city in Ladakh, where Hanle is located) and hints at an international project. The phrase "that is..." implies that more information will follow.
* S: "...Exploring the possibility of setting up two large gamma-ray..." This phrase connects with the idea of the collaboration and adds what is being explored.
* P: "...Telescope arrays in the Northern and Southern hemispheres." This suggests that gamma-ray telescopes are involved, and they will likely have arrays in different hemispheres.
Putting it all together, the sequence RQSP forms a logical progression: India plans to offer an astronomical site at Hanle in Leh for an international collaboration that is exploring the possibility of setting up two large gamma-ray telescope arrays in the Northern and Southern hemispheres.
