In which of the following movements was the slogan- ’Vadakku Vaazhkiradhu; Therkku Thaekiradhu’ (The north thrives even as the south decays) used?

The correct option/answer is Dravidian movement.

Explanation:

The slogan "Vadakku Vaazhkiradhu; Therkku Thaekiradhu" (which translates to "The north thrives even as the south decays" or "The North prospers, the South depletes") was a prominent political slogan coined by C. N. Annadurai, a key leader of the Dravidian movement in Southern India.

This slogan was used to highlight the perceived economic, political, and cultural dominance of Northern India over the Southern states, and it became a rallying cry for the Dravida Munnetra Kazhagam (DMK) and the broader Dravidian movement to advocate for state autonomy and fair resource distribution.
