The Neti-pot Company ran a magazine ad that contained the following message:

"$100 reward will be paid by Neti-pot Co. to any person who suffers from hayfever after having used the Neti-pot three times daily for 4 weeks, according to the printed instructions supplied with the pot. We have deposited $1000 with First National Union Bank to show how much we believe in the healing powers of the Neti-pot."

Sheldon used the Neti-pot every day for 4 weeks, but still suffered from seasonal hayfever allergies. Will he be able to collect $100 from the Neti-Pot Company?

(a) No, because advertisement are not generally offers.

(b) No, because the advertisements are an invitation to bid.

(c) No, because no reasonable person would have believed Neti-pot's ad to be an offer.

(d) Yes, because Sheldon accepted the offer contained in the Neti-pot ad by performance.
