Task: Answer the multiple choice question.
Query: Which drug has a 9.947\% 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 other words.
Options:
a CCCOc1ccc(-c2nc3c(c(=O)[nH]c(=O)n3Cc3ccccc3)n2CCO)cc1OCC
b COc1ccc(/C=N/NC(=O)c2cccnc2)c2ccccc12
c O=C(CSc1nc2ccc(Cl)cc2[nH]1)NCCc1ccc(Cl)cc1
d COC(=O)C1CCN(c2c([N+](=O)[O-])cc(C(F)(F)F)cc2[N+](=O)[O-])CC1
Answer: d. COC(=O)C1CCN(c2c([N+](=O)[O-])cc(C(F)(F)F)cc2[N+](=O)[O-])CC1
