Diverticulosis is the presence of diverticula in the colon, often asymptomatic unless inflamed (diverticulitis).

Correct Answer is A
Explanation
A. Isotonic: An isotonic solution has the same solute concentration as blood plasma; thus, 0.9% NaCl does not cause cells to shrink or swell.
B. Exotonic: "Exotonic" is not a recognized term in fluid balance or physiology.
C. Hypotonic: A hypotonic solution (like 0.45% NaCl) has a lower solute concentration than blood, causing water to move into cells, possibly leading to swelling.
D. Hypertonic: A hypertonic solution (like 3% NaCl) has a higher solute concentration than blood, causing water to leave cells and leading to cell shrinkage.
