Task: Answer the multiple choice question.
Question: Which drug has a 0.711\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(Nc1nc2ccccc2n1CCN1CCCC1)c1ccc(Cl)cc1
b: CCC(C)(C)n1nnnc1C(c1cc2cc(C)ccc2[nH]c1=O)N1CCCc2ccccc21
c: O=C(NC(=S)Nc1cccc([N+](=O)[O-])c1)c1ccccc1
d: COc1ccc(S(=O)(=O)Cc2ccccc2)cc1N
e: CC(C)(C)c1ccc(C(=O)Nc2ccc(C=C(C#N)C#N)cc2)cc1
Answer: b. CCC(C)(C)n1nnnc1C(c1cc2cc(C)ccc2[nH]c1=O)N1CCCc2ccccc21
