Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.990\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CN(NC(=O)C(C)(C)C)c1nc(-c2ccccc2)nnc1C(F)(F)F
[b] Cc1ccc(S(=O)(=O)NNC(=O)C2CC=CCC2C(=O)O)cc1
Answer: a. CN(NC(=O)C(C)(C)C)c1nc(-c2ccccc2)nnc1C(F)(F)F
