The respiratory structure that contracts and relaxes to allow air to flow in and out of the lungs is option(c) i.e, the diaphragm.
<h3>What is
the diaphragm?</h3>
The diaphragm, a delicate skeletal muscle that separates the chest from the belly, is located at the base of the chest. When you breathe in, it flattens and shrinks. As a result, the lungs experience a vacuum effect that draws air in. The diaphragm relaxes and the air is forced out of the lungs when you exhale.
signs of diaphragm issues:
- Acid reflux, heartburn, coughing, and difficulty swallowing.
- alterations to skin tone (skin may turn blue).
- rapid heartbeat, pressure in the chest, and/or breathing difficulties (especially when lying down).
- Headaches.
- Hiccups that persist or recur frequently.
Patients who need surgery for conditions affecting the chest, including diaphragm issues, are treated by a thoracic surgeon.

<h3><u>Explanation:</u></h3>
The DNA is the genetic molecule of a cell in an organism that contains the genetic information stored in forms of genes. The genes are expressed by means of protein synthesis. The genes are formed of particular sequence of nitrogen bases that is called as codon. These codons are transcribed into particular amino acids. This process involves the participation of DNA dependent RNA synthase that produces the mRNA from the portion of DNA by means of transcription. The mRNA that is produced from the DNA is formed of complementary nitrogen bases from the DNA, just exception is that in RNA, thymine is replaced by Uracil. This process is known ad transcription.
