C Correct answer
Explanation

Rouleaux formation is the stacking of red blood cells (erythrocytes) like a pile of coins, which occurs due to the discoid shape of RBCs and increased plasma proteins (especially fibrinogen). This is distinct from agglutination (antibody-mediated clumping) and coagulation (clot formation). Rouleaux formation is a normal phenomenon that aids RBC transport through capillaries.
