Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.169\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) [O-]/C(=C(\C(=S)Nc1ccc(SC(F)F)cc1)[n+]1ccccc1)c1ccc(Cl)cc1Cl
(b) CCc1sc(C(=O)Nc2ncccc2O)cc1C
(c) C[C@H](N)c1nnc(SCC(=O)N(C)C)o1.Cl
Answer: c. C[C@H](N)c1nnc(SCC(=O)N(C)C)o1.Cl
