1c. D. The first two rules have different confidence value. For an association rule {a} -> {b}, confidence is the ratio of the number of orders in which a and b occur together to the number of orders a occurs. Confidence value of {p} -> {q} and {p} -> {q,r} will be different since number of orders in which p and q occurs is not the same as number of order p, q and r occur
