Answer: Option C - Lower latency compared to Medium Earth Orbit (MEO) satellites.

Explanation:

• Geostationary Earth Orbit (GEO) satellites, positioned at 35,786 km above the equator, provide continuous coverage of specific regions with minimal ground station tracking.
• They require fewer satellites for global coverage but suffer from high latency due to their distance from Earth.
• Medium Earth Orbit (MEO) satellites, at lower altitudes (2,000–35,786 km), offer reduced latency compared to GEO, making them preferable for applications like GPS and some communications networks.

Answer: Option B - A global satellite-based internet service by SpaceX

Explanation:

• Starlink is a satellite-based broadband internet service developed by SpaceX.
• It operates using a constellation of low Earth orbit (LEO) satellites to provide high-speed internet, particularly in remote and underserved areas.
• Unlike traditional satellite internet, Starlink offers lower latency and speeds of up to 250 Mbps.
• Its applications include supporting education, emergency response, and business operations in geographically isolated locations, making internet access more accessible worldwide.

Answer: Option A - India, Pakistan, Israel

• The United States, Russia, China, along with the United Kingdom, France, Germany, and Canada, Australia, Japan, are all NSG members.
• India has sought NSG membership but faces opposition, particularly from China.

Answer: Option A - Civil nuclear energy cooperation

Explanation:

• The "123 Agreement" refers to the India-US Civil Nuclear Agreement, signed in 2008, enabling US companies to supply nuclear fuel, reactors, and technology for India’s civilian nuclear energy program.
• It granted India access to global nuclear trade despite being a non-signatory to the Nuclear Non-Proliferation Treaty (NPT).
• In return, India committed to separating its civilian and military nuclear programs and allowing IAEA safeguards on civilian nuclear facilities.

Answer: Option A - Alexander Cunningham
