A placard at the entrance of a forest farm clearly stated: "It is forbidden to destroy the forest! Offenders are fine!" One day, nearby villager Yang went to the forest to cut a tree and was found by the forest farm ranger Zhang as he was going down the mountain Zhang not only criticized Yang, but also imposed fines on Yang. Yang was not convinced, and the two sides started a fierce argument. Yang said that I cut a tree and not a forest, and you should not punish me. Which of the following is Zhang's most logical rebuttal? ['Anyone who breaks the forest will be fined. A tree you cut is also a forest.', 'Chopping a tree is destroying the forest, and anyone who destroys the forest must be fined.', "I'm a forest ranger, and whoever doesn't protect the forest will be fined.", 'Protecting the forest is about education, and fines are not our goal.']
