Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.999\% 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] O=C(CN1C(=O)c2cccc3cccc1c23)N1CCN(Cc2ccc3c(c2)OCO3)CC1
[b] COc1cc(OC)c(S(=O)(=O)N2CCOCC2)cc1S(=O)(=O)N1CCOCC1
Answer: a. O=C(CN1C(=O)c2cccc3cccc1c23)N1CCN(Cc2ccc3c(c2)OCO3)CC1
