Ishmael purchases a whaling boat. When it is delivered, the boat dealer allows him to take it out to sea on a "trial run." Unfortunately the engine fails. Under Article 2 of the UCC, Ishmael

a.

may not reject the boat because Article 2 of the UCC prohibits that.

b.

may not reject the boat a reasonable time had passed before he discovered the defect.

c.

may reject the boat only if it sinks; in this case the dealer substantially performed.

d.

may reject the boat, having inspected it within a reasonable time after delivery.
