The correct answer is D. criticize.
To criticize is to express disapproval of someone or something. It can be done in a constructive way, offering suggestions for improvement, or in a destructive way, simply tearing someone or something down. In the context of the question, “Do not follow others,” the most likely meaning of “criticize” is to offer constructive criticism. This means that you should not simply follow what others do without thinking for yourself. You should evaluate their actions and ideas, and if you find that you disagree with them, you should offer your own suggestions for how things could be done better.
