Task: Answer the multiple-choice question.
Query: Which drug has a 12.007\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=C1NC(=O)c2cc(NC(=O)C3COc4ccccc4O3)ccc21
[b] COCc1cc(C)nc(OCC(=O)N/N=C\c2cc(C)n(-c3cccc(C(F)(F)F)c3)c2C)c1C#N
Answer: a. O=C1NC(=O)c2cc(NC(=O)C3COc4ccccc4O3)ccc21
