[Big City] Leona and Enoch Lived Next Door to Each

[Big City] Leona and Enoch lived next door to each other for over thirty years. In an effort to bring new business and jobs into the area, the Big City council planned to build a shopping center, business park, and hotel. Big City notified Leona and Enoch that it had the authority to seize their land for public use, and Big City would provide them temporary housing and $1,000 in moving expenses. Leona and Enoch filed suit.
-Big City also passed a regulation prohibiting any new construction on nearby private land in order to protect wildlife near the new shopping mall. Ivan had intended to build a house on his private property, but, because of the new regulation, his property is useless to him. Ivan meets with Yuri, an attorney, who says that Ivan is entitled to compensation for the government's actions. Is Yuri correct?

A) No, because Ivan still owns the land.
B) Yes, but only if Ivan is deprived of all economically beneficial uses of the land.
C) No, because eminent domain does not apply.
D) No, because the commerce clause allows him to sell the property.
E) Yes, because the government's actions violate the equal protection clause.
