Task: Answer the multiple choice question.
Question: Which drug has a 14.135\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(Cc1ccc([N+](=O)[O-])cc1)NCc1ccccc1Cl
b: COc1cc(C(=O)NNC(=O)C2CCCC2)cc(OC)c1OC
c: COc1ccc(OC)c2[nH]c(=O)c(CCNC(=O)c3ccc(S(=O)(=O)N4CCCC4)cc3)cc12
d: Cc1ccccc1S(=O)(=O)Nc1nc2ccccc2nc1NCCO
Answer: b. COc1cc(C(=O)NNC(=O)C2CCCC2)cc(OC)c1OC
