Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.120% 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 additional words.
Options:
a: CC1=NN(/C(=N\c2nnc(C)s2)Nc2ccc(C(C)(C)C)cc2)[C@H](c2ccc(C)cc2)S1
b: COC(=O)c1nc2ccc(N3CCOCC3)cc2c(C)c1C(=O)OC
c: O=C(Nc1ccc2nc(-c3ccc(Br)o3)[nH]c2c1)c1cccs1
d: Cl.Cn1c(=O)c2c(ncn2CCCC(=N)N2CCOCC2)n(C)c1=O
Answer: a. CC1=NN(/C(=N\c2nnc(C)s2)Nc2ccc(C(C)(C)C)cc2)[C@H](c2ccc(C)cc2)S1
