Correct Answer: B
Detailed Solution
NanoPlug was associated with the concept of an extremely small hearing aid, designed to be minimally visible when placed inside the ear.
It was proposed to use small components such as a microphone, microchip and receiver.
The microphone would receive sound from the surroundings, the microchip would process that sound, and the receiver would deliver the processed sound to the ear.
For its extremely small size, miniaturized components and nano-battery technology were considered important.
