In intestinal epithelial cells, a transport protein moves the bulky, polar glucose molecules through the membrane into the cytoplasm, while simultaneously transporting na through the membrane into the cell down its electrochemical gradient. which example correctly describes this cotransport of glucose and sodium

Secondary active transport by symporter.

Explanation:

Secondary active transport is known as an active transport which moves two different types of molecules or ions across a transport membrane. In this transport one of the molecules moves down its electrochemical gradient across the biological membrane, and this helps another molecule to move in the uphill direction against the concentration gradient.

In symport transport the molecules moves in similar direction across the membrane. So, this is the example of Secondary active transport by symporter.
