Task: Answer the multiple-choice question.
Query: Which drug has a 3.894\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(Cn1c(=O)oc2ccccc21)c1ccccc1
(b) COC(=O)c1ccsc1NC(=O)CN1C(=O)CCC1=O
