Jackie, an orange supplier, contracted with Jimmy's Sushi for the delivery of 50 crates of grade B oranges. Every three months, Jackie regularly sends Jimmy's Sushi 50 crates of grade B oranges. Due to an oversight, Jackie sent Jimmy's Sushi 50 crates of grade A oranges. In this case,
a) Jimmy's Sushi can reject the goods and demand the grade B oranges
b) Jackie must refund Jimmy's Sushi for the difference in value between grade A and grade B oranges
c) Jimmy's Sushi must accept the grade A oranges
d) Jackie is not liable because it was an oversight
