If Jack, the owner of a clothing wholesale outlet, agrees to sell Jill ten pairs of designer jeans, the fact that Jack allows Jill into the warehouse to select the ten pairs that she wants will amount to:

(a) An assignment of the right to select the jeans

(b) A delegation of the duty to retrieve the jeans- I don't think this is the correct answer

(c) An identification of the goods

(d) A nullification of the agreement
