Problem statement: Answer the multiple choice question.
Question: Which drug has a 20.761% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. COc1cccc(/C=N/Nc2cc(Cl)nc(C)n2)c1O
b. O=C(Nc1ccc(N2CCOCC2)cc1)C1CCN(S(=O)(=O)Cc2ccccc2)CC1
Answer: a. COc1cccc(/C=N/Nc2cc(Cl)nc(C)n2)c1O
