Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 9.899\% 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, c, d, or e without using any other words.
Options:
[a] CCOc1ccc(N2C(=O)CC(NCc3ccc(F)cc3)C2=O)cc1
[b] COc1ccc(CN(C)C(=O)CNC(=O)CNC(=O)c2ccc(Cl)cc2Cl)cc1F
[c] COCCCn1c(=O)c2sccc2n(Cc2ccccc2C)c1=O
[d] CCOC(=O)c1c(NC(=O)Cn2cnc([N+](=O)[O-])n2)sc2c1CCC(C)C2
[e] COc1ccc(-c2ccc(N)[n+](CCCC(=O)O)n2)cc1.[Br-]
Answer: c. COCCCn1c(=O)c2sccc2n(Cc2ccccc2C)c1=O
