Problem statement: Answer the multiple choice question.
Query: Which drug has a 7.338\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: S=C(c1ccc(Br)cc1)N1CCCC1
b: COc1ccc(N2C(=O)/C(=C\c3ccco3)N=C2SCC(=O)N(C(C)C)C(C)C)cc1Cl
c: CCOC(=O)c1nnn(-c2ccc([N+](=O)[O-])cc2)c1C
Answer: a. S=C(c1ccc(Br)cc1)N1CCCC1
