Task: Answer the multiple-choice question.
Question: Which drug has a 7.821\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(O)c1ccc(COc2ccc(Cl)cc2Cl)o1
[b] CN1CCc2c(sc(NC(=O)CS(=O)(=O)c3ccc(F)cc3)c2C(N)=O)C1.Cl
Answer: a. O=C(O)c1ccc(COc2ccc(Cl)cc2Cl)o1
