Problem statement: Answer the multiple-choice question.
Question: Which drug has a 8.136\% 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] COc1ccc(S(=O)(=O)NCc2cc(=O)n(C)c(=O)n2C)cc1F
[b] Cc1c(NC(=O)/C(C#N)=C/c2c(N3CCCCC3)nc3ccccn3c2=O)c(=O)n(-c2ccccc2)n1C
Answer: b. Cc1c(NC(=O)/C(C#N)=C/c2c(N3CCCCC3)nc3ccccn3c2=O)c(=O)n(-c2ccccc2)n1C
