A "wind farm" was constructed on the open land next to a gas station where a mechanic is employed. The huge windmills generated electrical power and oscillated at low speeds, resulting in very low-frequency but high-amplitude sound waves that caused extreme discomfort in a substantial minority of people. The mechanic is one of the people adversely affected by such sound waves; the vibrations from the windmills give him severe headaches and upset his immune system. If the mechanic brings an action for nuisance against the owners of the wind farm and loses, what is the most likely explanation?
(A) Sound waves are not the kind of physical phenomenon on which liability for nuisance can be based.
(B) The owners of the wind farm cannot generate power without producing the offending sound waves, despite their best efforts to find an alternative technology.
(C) At least six out of 10 people are not affected by low-frequency sound waves.
(D) The mechanic neither owns nor rents the gas station at which he works.
