Answer:

D) epithelial tissue

Explanation:

The exchange surfaces of the organisms are the site for an exchange of substances or gases. These surfaces mostly lie within the body and protect the exchange tissues. The exchange surfaces of multicellular organisms are lined with epithelial tissues. These tissues have tightly packed cells with little or no intercellular spaces. The epithelial tissues serve to protect the exchange surfaces. Sometimes, these epithelial linings are modified to perform an additional function. The exchange surfaces are finely branched or folded to have a very large area. The digestive, respiratory, and excretory systems all have such exchange surfaces.

Answer:

Active uptake (which I think you mean active transport) is important when the concentration gradient is against that of a certain substance, so it doesn't cross the membrane through diffusion or passive transport. It is sometimes necessary if a substance needs to move across a membrane but can't do so due to electrical charge or that there is a substance on the other side of the membrane preventing diffusion.
