Task: Answer the multiple choice question.
Query: Which drug has a 16.098% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Nc1nc2ccc(-c3nc4ccccc4o3)cc2s1
b: O=C(Nc1nc(-c2ccco2)c(-c2ccco2)s1)c1ccc([N+](=O)[O-])o1
c: Br.CC1(C)N=C(N)NC(Nc2ccc(Br)cc2)=N1
d: COc1cc(SC#N)ccc1N=Cc1c(C)[nH]n(-c2ccc(C)cc2)c1=O
Answer: b. O=C(Nc1nc(-c2ccco2)c(-c2ccco2)s1)c1ccc([N+](=O)[O-])o1
