Task: Answer the multiple-choice question.
Question: Which compound exhibits a 18.684\% 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. COc1ccc(/C=N/N=C2/NC(=O)C(c3ccccc3)S2)c(OC)c1
b. O=C(NC1CC1)C1=C[C@H](c2ccccc2)C[C@H](OCc2ccc(CO)cc2)O1
Answer: a. COc1ccc(/C=N/N=C2/NC(=O)C(c3ccccc3)S2)c(OC)c1
