Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.523\% 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] Cc1cccc(NC(=O)c2nc[nH]c2C(=O)NCC(=O)OCc2ccccc2)c1
[b] CCn1c(SCC(=O)O)nnc1-c1ccccc1OC
[c] COc1ccc2[nH]c(=O)c(C(c3nnnn3C3CCCC3)N3CCN(Cc4ccc5c(c4)OCO5)CC3)cc2c1
[d] COC(=O)c1sccc1NC(=O)Nc1ccc(F)cc1F
[e] O=C1CC(N2CCN(Cc3ccccc3)CC2)C(=O)N1c1ccccc1
Answer: e. O=C1CC(N2CCN(Cc3ccccc3)CC2)C(=O)N1c1ccccc1
