[Skyrocketing Rent] Ethan Leased Space for His Health Food Store

[Skyrocketing Rent] Ethan leased space for his health food store from Simone. After a few years, Simone decided to sell the building in which the health food store was located to Mack. Simone told Ethan that the lease would be terminated and that whether he could stay or not depended on what he could work out with Mack. Mack told Ethan that he could stay only if he paid double the amount of rent he had been paying to Simone and that if Ethan complained, the rent would go even higher. Ethan told Mack that Simone had no right to make any changes and that he had the absolute right to continue paying the same set amount to Simone until the lease expired. The lease did not address transfers.

C) Ethan is correct only if he gave notice to Simone prior to the sale that he objected to it.
D) Ethan is correct only if there is less than one year left on his lease agreement.
