Problem statement: Answer the multiple-choice question.
Question: Which drug has a 16.959\% 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 other words.
Options:
a: Cn1c(=O)c2c(nc(NCc3ccccc3)n2CC(=O)NCc2ccccc2)n(C)c1=O
b: C/C(O)=C(\C#N)C(=O)Nc1cc(Br)ccc1Br
c: Nc1ccc(C(=O)N/N=C/c2cccc(Oc3ccccc3)c2)cc1
d: CCCCCCCSc1nnc(N)s1
Answer: b. C/C(O)=C(\C#N)C(=O)Nc1cc(Br)ccc1Br
