Answer to Question 1

ANS: B
Exercise-induced hemoglobinuria occurs in some individuals after repeated forceful effect of the feet on hard surfaces. This also may be called March hemoglobinuria.

Answer to Question 2

ANS: A
As red cells pass through fibrin deposits that have been abnormally formed inside the lumen of blood vessels, they are fragmented as the force of blood flow forces them through the fibrin. Red cell fragments may also be formed by turbulence of red cells as they pass over damaged endothelial cells that line the blood vessels.
