Answer:
The answer is: A) will not be formed because the flyer was sent out as an invitation to negotiate.
Explanation:
A flyer sent out to potential customers or buyers is an invitation for them to start negotiating a sale.
For example you receive a flyer on the street offering to sell TVs with a 15% discount. That doesn't mean you are going to buy the TV, but that you invited to approach the store and look for a TV you like and hopefully buy it. There even exists the possibility that the store ran out of TVs by the time you decide to go look for one, and that doesn't entitle you to sue them for not selling a TV to you.
