Answer:

<h2>c. increased vasomotor tone (tightening) of the capillaries in the area.</h2>

Explanation:

Such type of conditions in which redness takes place on the surface of the skin or in the mucous membrane is called erythema. There are many factors that cause erythema such as injury, inflammations and some others. Histamine plays an important role in the inflammatory process that leads to redness and some other conditions. During erythema and swelling tightening of the capillaries does not takes place.

Sulfur is an important element in the sulfur cycle. Sulfur compounds can be found on earth in various forms. They can be found in mineral rocks and organic matter. It is the <em>work of bacteria to reduce sulfur</em> compounds and convert them to sulfides.

There are different types of bacteria that reduce various sulfur containing compounds. They are <em>sulfate-reducing bacteria, sulfur-reducing bacteria, sulfite reducing bacteria etc.</em>  In a swamp there is  low oxygen availability and organic matter decays in this condition.

<em>The sulfate reducing bacteria oxidizes the organic matter  and releases Hydrogen sulfide.</em>
