Final Answer :
E
Explanation :
When a person stands in one place for a long period, gravity causes blood to accumulate in the veins of the feet and legs, increasing pressure in the venules and at the venous end of capillaries. This can lead to edema in the lower extremities due to the impaired return of blood to the heart and fluid accumulation.
