Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.808% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) CN(C)CCCN(C(=O)c1ccc(S(=O)(=O)N2CCOCC2)cc1)c1nc2cc3c(cc2s1)OCO3.Cl
b) CCc1ccc(C(=O)NNc2ccc(C)c(Cl)c2)cc1
c) [O-]C1=N/[N+](=C/c2ccccc2)CC1
d) CC(C)CN1CCN(Cc2c(F)cccc2Cl)CC1CCO
Answer: c. [O-]C1=N/[N+](=C/c2ccccc2)CC1
