Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -17.182\% 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(=O)Nc1c2c(nn1-c1ccc(C)cc1)CS(=O)(=O)C2
b. CC1=NN(C(=O)c2csc(C)c2)C(O)(C(F)(F)F)C1
c. CN(C)c1ccc(/C=N/NC(=O)CNC(=O)c2ccco2)cc1
d. CCN1CCN(c2ccc(N3CCN(S(=O)(=O)c4cc([N+](=O)[O-])ccc4C)CC3)nn2)CC1
e. O=C(O)c1ccc(COc2c(F)c(F)cc(F)c2F)cc1
Answer: d. CCN1CCN(c2ccc(N3CCN(S(=O)(=O)c4cc([N+](=O)[O-])ccc4C)CC3)nn2)CC1
