Task: Answer the multiple-choice question.
Query: Which drug has a 6.816\% 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 Cn1c(/C=C/c2ccccc2[N+](=O)[O-])nc2ccccc2c1=O
b CCN(CC)c1ccc2c(C)c(CN3CCOCC3)c(=O)oc2c1
c O=C1CSc2nc3ccccc3n21
Answer: a. Cn1c(/C=C/c2ccccc2[N+](=O)[O-])nc2ccccc2c1=O
