Task: Answer the multiple choice question.
Question: Which drug has a 8.209\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. O=C(O)COc1ccccc1/C=N/NC(=O)c1cccc(S(=O)(=O)N2CCOCC2)c1
b. CCN(CC)S(=O)(=O)c1ccc(Cl)nc1
Answer: b. CCN(CC)S(=O)(=O)c1ccc(Cl)nc1
