Task: Answer the multiple-choice question.
Query: Which compound has a 0.398\% 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(N[C@@H](Cc1ccccc1)C(=O)OCc1ccccc1)c1nc[nH]c1C(=O)NCc1ccccc1
[b] O=C(NC1(C(F)(F)F)NC(=O)N(c2ccc(F)cc2)C1=O)c1ccncc1
Answer: a. O=C(N[C@@H](Cc1ccccc1)C(=O)OCc1ccccc1)c1nc[nH]c1C(=O)NCc1ccccc1
