The original name of Karnataka when it was formed:

The correct answer is: A) Kannada Nadu

Kannada Nadu was the original name of Karnataka when it was formed on November 1, 1956. The state was formed by merging the Kannada-speaking areas of the erstwhile Bombay Presidency, Madras Presidency, and Hyderabad State. The name “Kannada Nadu” means “Land of Kannada” in the Kannada language.

The other options are incorrect because:

• Option B, “Mysore State”, was the name of the state before it was renamed Karnataka in 1973.
• Option C, “Greater Karnataka”, is a term that is sometimes used to refer to the larger region that is inhabited by Kannada speakers.
• Option D, “Karnatakam”, is a Sanskrit name for Karnataka.

I hope this helps! Let me know if you have any other questions.
