Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 17.368\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(Nc1nccs1)c1cc(-c2ccncc2)nc2ccccc12
b) CC(=O)NCCC(=O)Nc1cc(S(=O)(=O)Nc2ccc(Cl)cc2)ccc1N1CCCC1
Answer: a. O=C(Nc1nccs1)c1cc(-c2ccncc2)nc2ccccc12
