Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -10.477\% 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 additional words.
Options:
a: Cc1ccnc(NC(=O)c2ccc(NC(=O)c3ccco3)cc2)c1
b: C/C(=N\NC(=O)c1ccccc1NC(=O)c1ccc(Cl)cc1)c1ccncc1
c: CC(=O)N(C1CC(C)C(C#N)(C#N)C1(C#N)C#N)N(C)C
d: NS(=O)(=O)c1ccc(CNC(=S)NC2CCCCC2)cc1
e: O=[N+]([O-])c1ccc(C2=Nn3c(Cn4nnc5ccccc54)nnc3SC2)cc1
Answer: c. CC(=O)N(C1CC(C)C(C#N)(C#N)C1(C#N)C#N)N(C)C
