(A) which is a substance that promotes blood clotting, but not seriously interfering
(B) a substance that promotes blood clotting, but not seriously interfering
(C) a substance that promotes blood clotting, but does not seriously interfere
(D) which is a substance to promote blood clotting, but does not seriously interfere
(E) which is a substance that promotes blood clotting, but not a serious interference


Why option D is incorrect? somebody please help.
Thanks

Now, Original sentence says that thromobroxane is a substance that promotos blood clotting < Basically a general fact about it> but D says that thromobroxane is a substance whose puspose is to promote the blood clotting.

I believe now you can see that D is not what original sentence is trying to communicate.

Hope it helped you.

Can someone please explain why 'a low does of aspirin' and 'interfere' are correct. Should it not be 'interferes'?

You're correct that the following would be a clear subject-verb error:

    "A low dose of aspirin interfere with the production of prostacyclin."

That's definitely not good, since "dose" is a singular noun, and "interfere" is the plural form of the verb. Trouble is, that's not actually the construction we see in this sentence. There's a helping verb in the sentence ("does") -- and in many cases, a helping verb can change the form of the main verb. What we actually see is the following:

    "A low dose of aspirin does not interfere with the production of prostacyclin."

And this is fine: "does" is the singular form of the helping verb "to do", so we're all good.

I hope this helps a bit!
