Answer 1

Hint: First understand what is sound. Then find out how humans produce sound. Also, get an idea of location from where sound is produced. Using the information you will be able to reach the correct answer.

Complete step by step answer:
Sound is what we hear from our ear every-day. We hear different sounds because properties of sound like pitch, amplitude and frequency varies according to source of sound. For example, males have voices with more amplitude while females have a voice with high pitch.
Now, a question arises how do we produce sound. We produce sound using a voice box also known as larynx. This voice box is located on the upper part of the windpipe.
Thus, all the options A,B,C given in the question are correct. Thus, the correct answer is option D.

Additional Information:
-Sound travels in the form of a wave. In sound waves particles vibrate in the direction parallel to the direction of the wave.
-Speed of sound varies according to the medium in which it travels. It is maximum in solids while it is minimum in gases.

Note: Carefully observe and understand all the options. Study in detail about sound produced in humans as you might be aware of any one option only. But here all the options A,B,C are correct. And if you select any one of the options from A,B,C then your answer will be considered incorrect.
