Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 3.975% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1cccc(CNC(=O)c2ccc(NC(=O)CC3SC(N4CCCCC4)=NC3=O)cc2)c1
b: CC(Sc1nc2c(cc1C#N)CCCCC2)C(=O)O
c: CCc1nc(N2CCCC2)c(C#N)c2c1CCCC2
d: CC(C)(C)c1ccc(OCCC(=O)OCC(=O)NC2CC2)cc1
e: CCOc1ccc(/C(C)=N/N2C(=O)C(CC(=O)Nc3ccc(OC)cc3[N+](=O)[O-])SC2=Nc2cccc(C)c2C)cc1
Answer: c. CCc1nc(N2CCCC2)c(C#N)c2c1CCCC2
