What is the Chronological order of sanskrit Tamil Telugu and kannada based on year in which they were given classical status?

Here's the chronological order of the four languages based on their classical language status in India:

1. Tamil: Declared a classical language in 2004.

2. Sanskrit: Declared a classical language in 2005. This is a bit tricky, as Sanskrit has been considered a classical language for centuries, but the official declaration came in 2005.

3. Telugu: Declared a classical language in 2008.

4. Kannada: Declared a classical language in 2008.

Therefore, the order is Tamil, Sanskrit, Telugu, and Kannada.
