Task: Answer the multiple choice question.
Question: Which drug has a 12.808\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. CC1(c2ccc([N+](=O)[O-])c(CS(=O)(=O)c3ccccc3)c2)OCCO1
b. O=C(Cc1csc(-c2ccc(F)cc2)n1)Nc1cccc(S(=O)(=O)NC2=NCCC2)c1
Answer: a. CC1(c2ccc([N+](=O)[O-])c(CS(=O)(=O)c3ccccc3)c2)OCCO1
