1) During this experiment, a positively charged rod is brought near but not touching the electroscope. The presence of the charged object above the plate of the electroscope induces charges to move down into the gold leaves, giving the electroscope an overall positive charge. The positive leaves repel. Which statement(s) in the prompt is/are key to explaining why the plate at the top of the electroscope contains negatives charges?
A) I
B) IV
C) III
D) II and III
