The intensification of the global flow of goods, services, ideas and people is defined as:

Globalization

The correct answer is option 3 - Globalization

Globalization as a concept fundamentally deals with flows. These flows could be of various kinds — ideas moving from one part of the world to another, capital shunted between two or more places, commodities being traded across borders, and people moving in search of better livelihoods to different parts of the world. The crucial element is the ‘worldwide interconnectedness’ that is created and sustained as a consequence of these constant flows.
