Solution

The correct option is A Absorbed rapidly by active transport with sodium ions.
Glucose is a crucial energy source, and it is important in many cellular processes.
The major site of glucose absorption in the body is the epithelial cells of the small intestine.
The mechanism in epithelial cells of the small intestine is possible when glucose absorption was coupled with Na+ transport.
The Na+-glucose cotransporter is a key transport protein that is responsible for absorbing Na+ and glucose from the luminal contents of the small intestine and reabsorption by the proximal straight tubule of the nephron. Hence, In a rabbit, when a dilute solution of glucose reaches the small intestine, it is absorbed rapidly by active transport with sodium ions.
So, the correct answer is 'Absorbed rapidly by active transport with sodium ions'.
