Task: Answer the multiple-choice question.
Question: Which drug has a -0.284\% 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. O=C(Cc1c(O)c2ccccc2oc1=O)c1ccc(F)cc1
b. O=C(/C=C/c1ccc(Br)o1)Nc1cc(S(=O)(=O)Nc2ccccc2Cl)ccc1Cl
Answer: b. O=C(/C=C/c1ccc(Br)o1)Nc1cc(S(=O)(=O)Nc2ccccc2Cl)ccc1Cl
