The RNA-first hypothesis suggests that RNA was the first molecule to emerge and act as both genetic material and a catalyst, leading to the development of more complex molecules such as DNA and proteins. However, it does not propose that DNA and proteins were necessary for the chemical evolution that led to the development of the first cells. Therefore, statement D is not true.
