The correct answer is (C) Trees.
The Chipko Movement is a grassroots environmental movement that originated in the state of Uttarakhand, India, in the 1970s. The movement is known for its nonviolent protests and efforts to protect trees and forests from deforestation. The term "Chipko" means "to hug" or "to cling" in Hindi, which symbolizes the act of embracing trees to prevent them from being cut down. The Chipko Movement emerged as a response to rampant logging and deforestation, aiming to conserve forests, preserve biodiversity, and protect the livelihoods of local communities dependent on forests.
