Task: Answer the multiple choice question.
Query: Which compound exhibits a 6.693\% 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, or c without using any additional words.
Options:
a COC(=O)/C(=N/Nc1cccc(C)c1)N1CCCc2ccccc21
b CSCc1cc(N2CCOCC2)nc(SCc2ccc(Cl)c(Cl)c2)n1
c CC(=O)C1=C(C)Nc2ncnn2C1c1ccccc1Cl
Answer: c. CC(=O)C1=C(C)Nc2ncnn2C1c1ccccc1Cl
