answer is D. have an enzematic specificity similar to trypsin
thrombin has a specificity for arginine-glycine bonds in a manner similar to trypsin.

Good question, remember thrombin cleaves fibrinogen :arrow: fibrin (excluding C)...it is not a vitamin K dependent factor (excluding B and E), and A is too non-specific.

Given a similar enzyme (proteolytic), we should think that the two have similar actions in some manner.
