Task: Answer the multiple choice question.
Question: Which compound has a -4.146% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(NCc1ccccc1)C1=C[C@H](c2ccc(Br)cc2)C[C@H](OCc2ccc(CO)cc2)O1
b. COC(=O)c1ccc(NC(=O)c2nc(S(=O)(=O)Cc3cccc(C)c3)ncc2Cl)cc1
c. O=C1CSC(c2cn(-c3ccccc3)nc2-c2cc3ccccc3oc2=O)N1Cc1ccccc1
d. CCOC(=O)C1C(=O)CC(C)(O)C(C(=O)OCC)C1c1ccc(OC)cc1
Answer: d. CCOC(=O)C1C(=O)CC(C)(O)C(C(=O)OCC)C1c1ccc(OC)cc1
