Task: Answer the multiple-choice question.
Query: Which drug has a 4.625\% 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] COc1cc(CN2CCCC(C(=O)c3ccc4c5c(cccc35)CC4)C2)cc(OC)c1O
[b] O=C(Cc1cccs1)Nc1ccccc1C(=O)O
Answer: b. O=C(Cc1cccs1)Nc1ccccc1C(=O)O
