Problem statement: Answer the multiple choice question.
Query: Which compound has a 3.334\% 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, or d without using any additional words.
Options:
a Oc1ccc(C[C@@H]2CNC(=S)N2CCc2cc(C(F)(F)F)cc(C(F)(F)F)c2)cc1
b CCOC(=O)N1CCN(C(=O)C(C)c2ccc([N+](=O)[O-])cc2)CC1
c CCn1cc(/C=C/C(=O)Nc2ccc(C)cc2Br)cn1
d CCn1cc(C(=O)NCc2cccc(F)c2)c(=O)c2cc(F)c(N3CCN(C(=O)c4ccco4)CC3)cc21
Answer: d. CCn1cc(C(=O)NCc2cccc(F)c2)c(=O)c2cc(F)c(N3CCN(C(=O)c4ccco4)CC3)cc21
