Mr Leghorn Lives Next Door to Mr

Mr. Leghorn lives next door to Mr. Fudd. During hunting season, Mr. Fudd likes to shoot rabbits in his backyard, an activity which he values at $900. The noise from the shooting disturbs Mr. Leghorn and prevents him from taking afternoon naps, which he values at $500. If Mr. Leghorn has the legal right to stop Mr. Fudd from hunting, the socially optimal outcome is for:

A) Mr. Fudd to stop hunting.
B) Mr. Fudd to pay Mr. Leghorn between $500 and $900 to continue hunting.
C) Mr. Leghorn to pay $500 or less to get Mr. Fudd to stop hunting.
D) Mr. Fudd to pay Mr. Leghorn less than $500 to continue hunting.
