Task: Answer the multiple choice question.
Question: Which compound has a 6.837\% 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: CC(=O)N1CCN(CC(=O)Nc2ccccc2Sc2ccc(Cl)cc2)CC1
b: O=C(COC(=O)c1ccc2c(c1)OCO2)Nc1nc(-c2ccccc2)cs1
c: CC(C)C(=O)Nc1ccc(-c2nc3ncccc3o2)cc1
d: O=C(C[n+]1cccc2ccccc21)c1ccc(NC(=O)c2ccccc2)cc1.[Br-]
e: O=C1NC(=S)N/C1=C/c1ccc(Oc2ccc(C(F)(F)F)cc2[N+](=O)[O-])c(Cl)c1
Answer: c. CC(C)C(=O)Nc1ccc(-c2nc3ncccc3o2)cc1
