The best answer is B.  Transudate.

 

Transudates and exudates are both forms of extracellular fluid.  Transudates occur with intact capillary-tissue interface, and result from increased pressure in the capillaries (such as in heart failure) low serum proteins (e.g. Liver disease), kidney disease, etc.  Transudates have low protein content and specific gravity.  Thus, the concept of transudate involves bodily fluids and electrolytes.

 

Exudates are extracellular fluids occurring when disease alters the capillary-tissue interface, allowing fluids with high protein content and specific gravity to escape the blood vessels.  Most exudates result from inflammation.  They have little to do with water and electrolytes.

 

“Serosanguinous” is an adjective describing a bodily fluid that is composed of a mixture of blood and serum.  It is really a descriptive term for fluid in the body having a somewhat watery (serous) consistency, and pink or red color from admixed blood.  Transudates and exudates may be serosanguinous, however exudates are often thicker and not really watery.

 

“Induration” means hardening.  It is loosely related to the other terms in that if transudates or exudates accumulate beneath the skin, for example, the tissues may be distended and hardened to palpation by the examiner, and described as Induration.

 

The reference distinguishes transudate from exudate.
