Which change would cause the largest increase in a mountain climber’s gravitational potential energy? carrying twice the weight and climbing half as high carrying half the weight and climbing half as high carrying twice the weight and climbing twice as high carrying half the weight and climbing twice as high

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
