Which statement best describes the color and volume percentage of plasma in blood?

The statement that describes the color and volume percentage of plasma in blood as yellow and 55% is accurate because plasma is the liquid component of blood, primarily composed of water, electrolytes, proteins, hormones, and waste products. It takes on a pale yellow color due to the presence of substances such as bilirubin and various proteins.

In terms of volume, plasma constitutes about 55% of total blood volume in a healthy adult, making it the largest component of blood. This percentage can vary in individuals, but this figure is generally accepted in physiology. The other options do not accurately represent the characteristics of plasma; for example, red is the color of red blood cells, not plasma, while clear and blue are not representative of plasma's normal appearance.
