In India, we use the DD-MM-YY format. This is an example of which concept?

Westernisation

The correct answer is Option (3) → Westernisation

This concept refers to the adoption of cultural traits, technologies, and practices from the West. While India has its own traditional calendars, the DD-MM-YY date format is a standard used across many European and other Western countries, and its widespread adoption in India for official and common use reflects the influence of Western cultural and administrative systems.
