I've got the following question and I'm afraid that the question doesn't match with the answer...

Factor III (rather than factor VIII) is known as thromboplastin or tissue factor and it makes sense that the factor III deficiency is related to thromboplastin formation. Isn't it?

What does factor VIII have to do with thromboplastin formation?

    $\begingroup$ OP is still confused because the question he/she is quoting has a wrong answer. The correct answer is C. $\endgroup$ – user24284 May 27 '17 at 13:45

    $\begingroup$ @anongoodnurse Regarding to research, I did a lot, and also discussed with my friends on Whats-app group, I came here as a last resort. We have a confusion about this question. I'm confused because the factor III by itself is thromboplastin and since it's absent, then we don't need to talk about absence of factor VIII which interrupt thromboplastin formation (and by the way it is by itself not so clear, because factor III takes place before factor XIII works), I hope I explained myself well. $\endgroup$ – Alleged Biologist May 27 '17 at 13:56

    $\begingroup$ As far as I can see from OMIM omim.org/entry/134390 there are no hereditary conditions associated with FIII deficiency so I think it unlikely that it is a VIII/III typo. I agree with @GerardoFurtado, if the asterisk is indicative of the 'correct' answer then this is a mistake in the question (or actually in the answer to the question). $\endgroup$ – Alan Boyd May 27 '17 at 16:00
