Task: Answer the multiple-choice question.
Question: Which drug has a -0.512\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=[N+]([O-])c1ccc2[nH]c3c(c2c1)CCCC3O
b) COc1cccc(C2c3[nH]c4ccccc4c3CCN2C(=O)c2ccccc2F)c1OC
c) CCN(c1ccccc1)S(=O)(=O)c1ccc(F)cc1C
Answer: c. CCN(c1ccccc1)S(=O)(=O)c1ccc(F)cc1C
