Problem statement: Answer the multiple choice question.
Query: Which compound has a 3.967\% 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(C)(C)Nc1nc(SCc2ccccc2)nc(N2CCOCC2)n1
b: Cc1cccc(Nc2nc(-c3ccc4c(c3)OCCO4)cs2)c1
c: COC(=O)c1cccc(-n2[nH]nnc2=S)c1
d: CC(=O)Nc1ccc(OCC(O)CN2CCN(c3ccc(C)c(Cl)c3)CC2)cc1
e: C[C@H](N)CN1CCc2ccc(Br)cc21.O=C(O)/C=C/C(=O)O
Answer: e. C[C@H](N)CN1CCc2ccc(Br)cc21.O=C(O)/C=C/C(=O)O
