Task: Answer the multiple choice question.
Query: Which compound has a 17.193\% 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) O=C(c1cccc([N+](=O)[O-])c1)N1CCc2ccccc21
(b) COc1ccccc1NC(=O)c1ccc(N2CC3CC(C2)c2cccc(=O)n2C3)c(NC(=O)c2ccncc2)c1
(c) O=c1c2c(ncn1CCO)nc1n2CCC1
(d) CCOC(=O)c1c(-c2ccccc2)csc1NC(=O)/C(C#N)=C/c1ccc(OC)c(OC)c1
Answer: a. O=C(c1cccc([N+](=O)[O-])c1)N1CCc2ccccc21
