The correct answer here is B: Entrepeneurship. The reason for this being the correct answer is that John is establishing a new business, something that is even novel because people don´t usually raise chickens to get eggs in the city and it answers the needs of city-living people, instead of having to rely on eggs that are grown from chickens who live in the country. Entrepneurship is defined as a business activity that is established by a person, who is called an entrepeneur, that is completely new and that answers to the needs and trends of the market, which is the case of John.
Any word would be fine but if you love that car you would say something like Wow! or Cool! or Ahhhhhhhh! Maybe a shriek or a hug? Maybe Yay? It could be anything you want.
