Task: Answer the multiple choice question.
Question: Which compound has a 16.642\% 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 COc1cc(/C=C/C(=O)O)cc(S(=O)(=O)N(CC(C)C)CC(C)C)c1OC
b CCC(C)[C@H](N)c1nnc(SCc2cccc(F)c2)o1.Cl
c Nc1c(-c2ccccc2)c(CSc2nc3ccccc3[nH]2)nn1-c1cccc(C(=O)O)c1
d O=C1CCCN1CCCNc1ncnc2c1[nH]c1ccccc12
Answer: d. O=C1CCCN1CCCNc1ncnc2c1[nH]c1ccccc12
