Task: Answer the multiple-choice question.
Query: Which compound exhibits a 4.421\% 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. CCCc1nc2sc3c(=O)n(N)cnc3c2c2c1CCCC2
b. CCOP(=O)(OCC)C(NC(=O)Nc1ccccc1)C(N)=O
c. COCCNC(=O)N1[C@H]2CC[C@@H]1C(C(=O)OC)=C(c1ccc(-c3ccccc3)c(F)c1)C2
d. O=c1c2ccccc2nc(SCc2ccc([N+](=O)[O-])cc2)n1-c1ccc(Cl)cc1
Answer: d. O=c1c2ccccc2nc(SCc2ccc([N+](=O)[O-])cc2)n1-c1ccc(Cl)cc1
