Task: Answer the multiple choice question.
Query: Which compound has a 5.329\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. CCN1CCN(Sc2ccccc2[N+](=O)[O-])CC1
b. CCN(CC)S(=O)(=O)c1ccc(N2CCCC2)c(N=Cc2c(C)nn(-c3ccccc3)c2Cl)c1
c. CCOP(=O)(OCC)c1cccc(OP(=O)(c2cccc([N+](=O)[O-])c2)c2cccc([N+](=O)[O-])c2)c1
d. O=C(NCCCNC(=O)c1ccco1)c1ccc(F)cc1
e. CCC(C)C1NC(=O)C(C(C)=O)=C1O
Answer: a. CCN1CCN(Sc2ccccc2[N+](=O)[O-])CC1
