The development of the concept of 'Global Village' is mainly based on:

The correct answer is C. The idea of the 'Global Village' rests on transport and communication development, which shrank the effective distance between people and nations. Marshall McLuhan popularised the term in the 1960s, arguing that electronic media such as radio, television and later satellite links made the world feel like one neighbourhood, where events in one place are known almost instantly everywhere.

• A (Social development): Social change is a consequence of the global village, not its foundation. Shared norms and cultures spread because of the connectivity that already existed.
• B (Political development): Political systems can be affected by connectivity, but political development does not physically bring the world closer. The question asks about the underlying basis.
• D (International organisations): Bodies like the UN or WTO facilitate cooperation, but they operate on top of the communication network. They are an institutional response, not the base.

For Mains, this links directly to globalisation, the digital economy, and the role of ICT in governance and social change. A good answer would show how time-space compression changes both opportunities and vulnerabilities, such as the speed of misinformation.

Trap: Aspirants often pick D because global institutions look like the obvious 'global' link. Ask what makes the connection possible in the first place.
