Answer: It’s MICROPHONE

Explanation: from PF book

A transmission system at a radio station consists of these devices:

1. Anoscillator,whichconvertsadirectcurrentintoahigh- frequency alternating current

2. Atransmittingantenna,whichsendsoutradiowaveshavingthe same frequency as the current supplied by the oscillator

3. Amicrophone,whichpicksupthesoundwavesandconverts them into a suitable electric current with the same pattern as the sound waves

4. A modulator, which enables the waves produced by the antenna to “carry” the pattern of the sound waves picked up by the microphone

What are the "following" devices ? ?
I think they're a list of choices that you have but aren't sharing.

A few devices associated with the reception of various types of
radio signals include the resonant tank, the local oscillator, the
mixer, the detector, the coherer, the discriminator, the parabolic
reflector, the lecher wires, the audio transducer, the demultiplexer,
and ... my personal guess ... the 'antenna' or 'aerial'.

Balboa Park in San Diego has an outdoor organ. When the air temperature increases, the fundamental frequency of one of the organ
musickatia [10]

The fundamental frequency of one of the organ pipes will go up or increase.

When pressured air is forced into an organ pipe, it echoes at a particular pitch, generating the sound of the pipe organ. Each pipe has been adjusted to a particular pitch on the musical scale.

A musical instrument called an outdoor pipe organ is used to perform music. It produces some calming tones and has a really serene sound. The organ pipe produces the sound of the outdoor organ. The wavelength of the sound is also dependent on the length of the pipe. The fundamental frequency of one of the organ pipes will grow as the speed of the sound increases as the ambient air temperature rises.

The correct option is (c).
