Task: Answer the multiple-choice question.
Question: Which compound exhibits a -1.020\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e 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.) COc1cccc(NC(=O)Nc2nc(-c3ccc(OC)c(OC)c3)cs2)c1
c.) COC(=O)COc1ccc(S(=O)(=O)NCCC2=CCCCC2)cc1
d.) CN1C(=O)[C@H](Cc2ccc([N+](=O)[O-])cc2)NC1=S
e.) CC(O)[C@H]1CNC(=O)C(=O)N1CC1(c2ccccc2)CC1
Answer: a. O=C(NCc1ccccc1)C1=C[C@@H](c2ccc(Br)cc2)C[C@@H](OCc2ccc(CO)cc2)O1
