Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -7.826% 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, or d without using any other words.
Options:
a: CCn1nnc(NC(=O)COc2ccc(C3CCCCC3)cc2)n1
b: CCS(=O)(=O)c1nc(S(=O)(=O)c2ccc(C)cc2)c(NCc2ccccn2)s1
c: COc1nccc(Nc2ccccc2)c1C#N
d: COc1ccc(NC(=O)N/C=C/c2ccc(Cl)cc2)cc1
Answer: c. COc1nccc(Nc2ccccc2)c1C#N
