Answer Key : (a) -

(a)

If air conduction and bone conduction showed a similar degree of hearing loss, the subject would have sensorineural hearing loss. The ear is most sensitive to frequencies between 1 kHz and 3 kHz. The endolymph is not an ultrafiltrate of plasma but is rich in potassium and low in sodium.
