Task: Answer the MCQ question.
Question: Which drug exhibits a 13.333\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] CC(=Nc1ccccc1N)c1c(O)n(C)c(=O)n(C)c1=O
[b] CCCNc1nc(Nc2ccc(C)c(Cl)c2)c2cnn(C)c2n1
[c] CC(C)CCn1c(COc2ccccc2)n[nH]c1=S
[d] O=C(/C=C/c1cccc(Cl)c1)c1ccc([N+](=O)[O-])o1
