Choice A rationale:

Purulent drainage is thick and often has a foul odor. It is often a sign of infection and can have a variety of colors, including yellow, green, or brown. This is not the correct choice because the description does not match the question.

Choice B rationale:

Serous drainage is clear and watery, often seen in normal healing processes. This is not the correct choice because the description does not match the question.

Choice C rationale:

Sanguinous drainage is fresh blood, often seen in deep wounds or when a wound is disturbed. This is not the correct choice because the description does not match the question.

Choice D rationale:

Serosanguineous drainage is a mixture of blood and serous fluid, often seen in new wounds. This matches the description given in the question.
