Choice "A" is correct. A buyer may reject goods if they do not conform to the contract in any way. This is known as the perfect tender doctrine. However, the mere fact that the goods do not meet the buyer's needs at the time of tender or delivery is not a ground for rejection if the goods conform to the contract.
Choices "d", "b", and "c" are incorrect. Each of these choices incorrectly address either I and/or II.
