Task: Answer the multiple choice question.
Question: Which drug has a 6.643\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: Cn1c(CNC(=O)Nc2cccc(Cl)c2)nnc1SCc1ccccc1
b: Cc1cc(C(C)(C)C)cc(C)c1CC1=NCCN1.Cl
c: CCCN(CC(=O)Nc1ccc(Cl)cc1Cl)C(=O)/C=C/c1cccc([N+](=O)[O-])c1
d: COc1ccc(-n2c(N)c(C#N)c3ccc([N+](=O)[O-])cc3c2=O)cc1
Answer: b. Cc1cc(C(C)(C)C)cc(C)c1CC1=NCCN1.Cl
