Task: Answer the MCQ question.
Query: Which drug has a 7.827\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(Cc1c(C(=O)O)[nH]c2ccc(Cl)cc12)Nc1ccc2c(c1)OCCO2
b: CCOc1ccc(N2C(=O)/C(=C\c3ccc(OC)c(O)c3)S(=O)(=O)C2c2cccc([N+](=O)[O-])c2)cc1
c: C=CCNc1sc(C(=O)c2ccc(Br)s2)c(N)c1C#N
Answer: b. CCOc1ccc(N2C(=O)/C(=C\c3ccc(OC)c(O)c3)S(=O)(=O)C2c2cccc([N+](=O)[O-])c2)cc1
