Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.148\% 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 additional words.
Options:
a: CCOC(=O)NC(N(O)c1cccc(Cl)c1)C(Cl)(Cl)Cl
b: C=CCOC(=O)C1=C(C)NC(SCC(=O)Nc2nccs2)=C(C#N)C1c1ccc(Cl)cc1
c: CCN(CC)c1ccc(/C=C(\C#N)C(=O)NCc2ccco2)cc1
d: Cc1nnc(NC(=O)CSc2ccc(-c3ccco3)nn2)s1
e: CCC(C)n1ncn(-c2ccc(N3CCN(c4ccc(OCC5COC(Cn6cncn6)(c6ccc(Cl)cc6Cl)O5)cc4)CC3)cc2)c1=O
Answer: a. CCOC(=O)NC(N(O)c1cccc(Cl)c1)C(Cl)(Cl)Cl
