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.

Mould growing on a tomato that is sitting on a countertop be used as evidence for the spontaneous generation theory.
<h3>What do you mean by spontaneous generation theory?</h3>
According to the hypothesis of spontaneous generation, the emergence of life things from nonliving materials was both common and predictable. It was proposed that some forms, like fleas, may develop from inanimate substances like dust or that maggots could develop from decomposing human flesh.
In addition to causing postharvest rot during harvest and storage, a gray mold of tomatoes can also spread a number of other diseases, such as damping off and blight. A fungus with a host range of over 200 plants causes gray mold on tomato plants. It will be evidence for spontaneous generation theory.
