Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.153% human ether-à-go-go related gene (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(OC)c(-c2csc(N(CC3CCCO3)C(=O)C3CCCCC3)n2)c1
[b] CC(=O)Nc1ccc(SCC(=O)OCC(=O)NC(=O)NCc2ccco2)cc1
[c] COCCN1C(=O)N[C@@H](CCc2ccccc2)[C@@H](C(=O)OC)[C@H]1C
[d] CCOc1ccc(-n2c(-c3ccc(Cl)cc3)c[n+]3c2SCC3)cc1.[Br-]
[e] CC(C)[C@H](NC(=O)Nc1cccc(Br)c1)C(=O)O
Answer: c. COCCN1C(=O)N[C@@H](CCc2ccccc2)[C@@H](C(=O)OC)[C@H]1C
