Task: Answer the multiple choice question.
Query: Which compound has a 18.227% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCOC(=O)c1c(C(=O)OCC)c(C)n(CCc2ccccc2)c1C
b. CCC(=O)N1CCN(CCN=CC2=C(O)CC(c3cccs3)CC2=O)CC1
c. Cc1csc(NC(=O)CSc2nnc3ncccn23)n1
d. O=C(O)C1Nc2c(O)cc(Cl)c([N+](=O)[O-])c2C2C=CCC12
Answer: d. O=C(O)C1Nc2c(O)cc(Cl)c([N+](=O)[O-])c2C2C=CCC12
