Answer»

The correct ANSWER is (a) True

For explanation I would SAY: It is true. Air conduction, by DEFINITION, is the transmission of sound through the external and middle ear to the internal ear.Bone conduction, on the other hand, refers to the transmission of sound to the internal ear mediated by mechanical vibration of the cranial bones and soft tissues.Clinical observation has shown that hard-of-hearing PATIENTS with middle ear disease usually have normal hearing by bone conduction, whereas patients with INNER ear involvement have decreased or diminished bone-conduction.
