Task: Answer the multiple-choice question.
Query: Which compound exhibits a 19.745\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=c1c2c3c(sc2nc(N2CCNCC2)n1-c1cccc(Cl)c1)CCCCC3
b COc1ccc(C(=O)Nc2ccc(C(=O)O)cc2NC(=O)c2ccc(OC)cc2)cc1
c COC/C=C/C1=CC2=CC(=O)C(C)(OC(=O)c3cccs3)C(=O)C2=CO1
d NNC(=O)c1ccc(COc2ccc([N+](=O)[O-])cc2)o1
Answer: c. COC/C=C/C1=CC2=CC(=O)C(C)(OC(=O)c3cccs3)C(=O)C2=CO1
