Which one of the following was given classical language status recently?

Odia is the correct answer because it was officially declared the sixth classical language of India in February 2014, making it the most recent addition at the time of the 2015 exam. Assamese is a tempting wrong option due to its ancient literary heritage, but it was not granted classical status until 2024. The core concept tested is the identification of languages recognized as "Classical" by the Government of India based on high antiquity and original literary tradition.
