Task: Answer the multiple-choice question.
Question: Which compound exhibits a 8.899\% 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=C1CSC(c2cn(-c3ccccc3)nc2-c2cc3ccccc3oc2=O)N1Cc1ccccc1
b Cc1ccc(-c2ccc(=O)n(CC(=O)NCCN3CCCCC3C)n2)cc1
c NC(=S)n1[nH]c(-c2ccc([N+](=O)[O-])cc2)c(N=Nc2ccc(O)cc2)c1=O
d O=C1C2CC=C(Cl)CC2C(=O)N1CCC[n+]1cccc2ccccc21
Answer: c. NC(=S)n1[nH]c(-c2ccc([N+](=O)[O-])cc2)c(N=Nc2ccc(O)cc2)c1=O
