The dependent variable is the variable being measured or observed in an experiment, which in this case is the number of correct items recalled on the memory test. The independent variable is the variable being manipulated, which in this case is the presence or absence of loud noise during the memory-encoding task. Therefore, A is the correct answer. B is the independent variable, C is not mentioned in the experiment description, and D is not a variable being measured or manipulated in the experiment.
