Task: Answer the multiple choice question.
Query: Which drug exhibits a -18.523% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1ccc(-c2nn(CC(=O)N(C)C)c(=O)c3ccccc23)cc1
b: NC(=O)COC(=O)c1cccc(S(=O)(=O)N2CCCCC2)c1
c: COc1cc(-c2cc(C(=O)Nc3ccc(S(=O)(=O)NCc4ccco4)cc3)c3ccccc3n2)cc(OC)c1OC
d: CCc1noc(C)c1C(=O)Nc1cc(S(=O)(=O)N2CCOCC2)ccc1OCC(F)(F)F
e: COc1ccccc1CN1CC(C(=O)NCCc2ccc(Cl)cc2)CC1=O
Answer: a. COc1ccc(-c2nn(CC(=O)N(C)C)c(=O)c3ccccc23)cc1
