Task: Answer the multiple-choice question.
Question: Which drug has a 15.419\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C(O)c1ccc2c(c1)S(=O)(=O)c1cc(Cl)ccc1C2=O
b CC(C(=O)O)n1c(C(F)(F)F)nc2ccccc21
c O=C(O)c1ccc(N2C(=O)CC(SC(=Nc3ccccc3)Nc3ccccc3)C2=O)cc1
Answer: a. O=C(O)c1ccc2c(c1)S(=O)(=O)c1cc(Cl)ccc1C2=O
