Task: Answer the multiple choice question.
Question: Which compound exhibits a 21.416\% 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 other words.
Options:
a: COc1ccccc1NC(=O)c1c(Nc2ccccc2C)sc(C(=O)Nc2cccc(Cl)c2)c1N
b: O=C1CC(c2cccc(Cl)c2)Cc2nc(N3CCN(c4ccccc4)CC3)ncc21
c: O=C(c1ccc(F)cc1)C1CCN(C(=O)c2ccc(F)cc2)CC1
d: O=C(CNC(=O)c1ccc(Br)cc1)N/N=C/c1ccc[nH]1
e: CCCOC(=O)c1ccc(NC(=O)CSC2=Nc3ccccc3C3CC=NN23)cc1
Answer: e. CCCOC(=O)c1ccc(NC(=O)CSC2=Nc3ccccc3C3CC=NN23)cc1
