It is true that once glucose, galactose, and fructose enter the absorptive cells, they are transported to the portal vein and then to the liver.
Absorptive cells are also known as enterocytes. These cells line the lumen of the small intestine and the colon. They are meant to absorb the nutrients from the digested food inside the lumen of intestine. Apart from absorption, they also transport the nutrients across the membrane.
Portal vein is the blood vessel that transports blood from the GI tract, pancreas, gall bladder and spleen into the liver. This blood vessels belongs to the portal venous system. Its location is the upper right quadrant of the abdomen.

C
Both animal and plant cells possess a nucleus and cell membrane however chloroplasts and a cell wall are only in a plant cell indicating that the answer must be C.

Specialized structures that perform cell functions are organelles.
What are cell organelles?
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
An organelle is a particular sort of cell structure. Organelles come in many different varieties. Vesicles are another name for organelles in a cell. They actually serve a purpose that is crucial since all of the processes in a cell must be compartmentalized. Therefore, a membrane is required to surround the processes inside a cell that produce diverse products. Organelles are therefore all membrane-bound in reality. They also distinguish between one function and another. So, for instance, the lysosome breaks down large molecules to make small molecules, while the mitochondrion produces energy by breaking down large molecules.
They must be divided up since the lysosome requires an acidic pH and the mitochondrion relies on all of its pathways, proteins, and enzymes to convert one chemical to another. Additionally, none of the functions would be created if those two substances were combined.
