Which of the following is LESS likely to result in edema?

A) Increase in capillary permeability
B) Reduced plasma colloid osmotic pressure
C) Blockage of veins
D) Increased mean arterial pressure
E) Loss of protein molecules in urine through the kidneys

Increased mean arterial pressure is less likely to directly result in edema compared to the other options. While it can contribute to conditions that might lead to edema, the direct mechanisms listed in the other options (such as increased capillary permeability, reduced plasma colloid osmotic pressure, blockage of veins, and loss of protein molecules in urine) have a more immediate and specific impact on the fluid balance between the intravascular and extravascular spaces, leading to edema.
