Kristen Hires Gabby to Babysit Her Three Children for the Day

Kristen hires Gabby to babysit her three children for the day. As soon as Gabby sees Kristen pull out of the driveway, she tells the kids to be quiet and just sit there because she wants to sleep. While Gabby sleeps, the wild children destroy the house. Is Kristen obligated to pay Gabby the price she agreed to for babysitting?

A) Yes, except Kristen would be able to deduct the damages that the kids did while the house while Gabby slept.
B) Yes because Gabby was indeed at the house the entire day and the courts do not require perfect performance.
C) No because while courts do not require perfect performance, they do require a good faith attempt at perfect performance.
D) No because the contract was illegal as the fact pattern does not indicate that Gabby was properly licensed to babysit.
