What meaning is indicated by the prefix "de-"?

Fingers, toes
Lack of, down
Half
Skin

The correct answer is: Lack of, down

The prefix "de-" signifies a meaning related to "lack of" or "down." This prefix often denotes removal, reduction, or reversal of a condition or state. For instance, "dehydrate" means to remove water from, indicating a lack of hydration. Similarly, in various medical and billing contexts, "de-" can suggest a downward trend or decrease in a particular area, such as a drop in a patient's condition or the reduction of a charge. The other options do not align with the meaning of the prefix "de-." Choices relating to body parts, quantities, or skin do not correspond to the definitions typically associated with this prefix in medical terminology.
