Answer:
D. The direction of filtration can be into or out of the blood, but reabsorption always involves fluids entering the blood.
Explanation:
I believe that this is the correct option since filtration can occur in blood vessels and lymphatics, that is why it can be inside or outside the blood, that is, the filtration can be bidirectional.
While the reabsorption is to be able to re-integrate it to the lumen of the capillary or the blood vessel, thus generating an uptake of certain chemical compounds, and this movement or flow is towards the interior of the capillaries, that is, towards the inside of the capillary.
