The first option, "Small chemical units joined into larger ones and eventually into cells," best describes the hypothesis of how life formed on Earth. This hypothesis suggests that simple organic compounds on Earth, such as amino acids, combined and formed more complex molecules that eventually led to the first cells. This process is known as chemical evolution or the prebiotic soup theory.
