Task: Answer the multiple choice question.
Query: Which drug has a 1.067\% 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. O=C(NCCCN1CCN(c2ccccc2F)CC1)C1CCCN(S(=O)(=O)c2cnc[nH]2)C1
b. COc1ccc(O)c(/C=N/n2c(-c3ccco3)csc2=Nc2cccnc2)c1
c. COc1coc(C(O)C[N+](=O)[O-])cc1=O
d. COc1ccc(-c2ccc(=O)n(Cc3c(F)cccc3Cl)n2)cc1
Answer: c. COc1coc(C(O)C[N+](=O)[O-])cc1=O
