Which are the basic components of a hearing aid?

Explanation:
The essential idea is the hearing aid’s signal path: sound is captured by a microphone, amplified by an amplifier, and then delivered to the ear by the receiver (the output transducer). The battery is the power source, not part of the signal-processing chain. So the best choice lists Microphone, Amplifier, and Receiver, covering input, processing, and output. Without the microphone, there’s no input; without the amplifier, the signal isn’t boosted; without the receiver, the amplified signal isn’t heard. The other options replace or omit one of these core parts or substitute the battery as a component, which leaves the device incomplete.
