    Correct Answer
    A. State the results.
    Explanation
    The correct answer is "State the results." In this scenario, after conducting the experiment where caterpillars consumed lettuce and tomato leaves, the next step would be to state the results of the experiment. This involves recording and presenting the data obtained from the experiment, such as the amount of lettuce and tomato leaves consumed by the caterpillars. Stating the results is an important step in the scientific method as it allows for the analysis and interpretation of the data, which then leads to drawing conclusions and forming new hypotheses for further experimentation.
