The correct option is A Blood has RBCs and WBCs while lymph has lymphocytes.
Blood is red in colour due to presence of RBCs. Blood plasma contains RBCs, WBCs and platelets. It can clot due to presence of more amount of fibrinogen. Lymphs are colourless due to absence of RBCs. The lymph plasma contains WBCs and lymphocytes. It contains diffusible proteins. It clots slowly due to presence of less fibrinogen.
