Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -22.874% 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: O=C(NCc1nc2ccccc2[nH]1)C1=C[C@H](C2CCCCC2)C[C@H](OCCCCO)O1
b: CCc1ccc(NC(=O)CSc2ccc(-c3ccccn3)nn2)cc1
c: O=C(CC1S/C(=N/N=C/c2cccs2)NC1=O)Nc1ccccc1F
d: O=C1c2cccc3cccc(c23)C(=O)N1OS(=O)(=O)c1ccc(Cl)cc1
Answer: a. O=C(NCc1nc2ccccc2[nH]1)C1=C[C@H](C2CCCCC2)C[C@H](OCCCCO)O1
