From which among the following are blood clotting factors released?

Platelets (thrombocytes) are cell fragments in blood that play a central role in haemostasis. Upon vascular injury, platelets adhere to the damaged site, aggregate, and release clotting factors (such as platelet factor 3, thromboxane A2, and other granule contents) that initiate and propagate the coagulation cascade leading to fibrin clot formation. RBCs primarily transport oxygen; eosinophils combat parasites and mediate allergic responses; monocytes differentiate into macrophages for phagocytosis.
