Task: Answer the multiple-choice question.
Question: Which compound has a -23.998% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. O=C(N/N=C/C=C/c1cccc([N+](=O)[O-])c1)c1ccncc1
b. Cn1cc(S(=O)(=O)N2CCN(c3cccc(Cl)c3)CC2)c(=O)n(C)c1=O
c. O=C1NC2(CCCCC2)Cc2ccccc21
d. CC(CCN1CCN=C1Nc1ccccc1)c1ccccc1
e. COc1ccc(N2CCN(S(=O)(=O)c3cc4c(cc3C)N(C(C)=O)CCO4)CC2)cc1
Answer: a. O=C(N/N=C/C=C/c1cccc([N+](=O)[O-])c1)c1ccncc1
