Step 1: Understand the question.
We must find what the Appiko movement is connected with. This is an environment movement question, so we think about forests and conservation.
Step 2: Find the meaning of the name.
The word Appiko comes from Kannada and means to hug or to embrace. This already tells us it is about people protecting something by hugging it.
Step 3: Recall a similar movement.
The Appiko movement was inspired by the Chipko movement of the north, where villagers hugged trees to stop them being cut. Appiko did the same idea in the south.
Step 4: Locate where it happened.
The Appiko movement took place in Karnataka, in the forest areas of the Western Ghats. The Western Ghats are rich in trees and wildlife.
Step 5: Understand the goal.
Villagers wanted to stop the cutting of forests in the Western Ghats and to save the local greenery and biodiversity. So the movement was about forest conservation in the Western Ghats.
Step 6: Match with the options.
The second option, Western Ghat forest conservation, fits perfectly.
\[ \boxed{\text{Western Ghat Forest Conservation}} \]
