Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.777\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) COc1ccccc1C(=O)Nc1ccc(S(=O)(=O)Nc2cc(C)nc(C)n2)cc1
(b) COC(=O)CN(c1cc(C(F)(F)F)ccc1Cl)S(C)(=O)=O
(c) CCCCOc1ccc(CON(C(C)=O)C(C)=O)cc1Cl
(d) Cn1c(SC2=CS(=O)(=O)c3ccccc32)nc2ccccc21
(e) C[N+](C)(C)CC#CCOC(=O)Nc1cccc(Cl)c1.[Cl-]
Answer: c. CCCCOc1ccc(CON(C(C)=O)C(C)=O)cc1Cl
