Task: Answer the multiple choice question.
Question: Which compound has a 9.991\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: Cc1ccc(/C=N/NC(=O)Cc2cccn2C)s1
b: Cc1ccc(-c2c(C#N)c(N)n(-c3ccc(C)cc3)c(=O)c2C#N)cc1
c: CCOC(=O)c1c(C)[nH]c(C(=O)OC)c1CCC(=O)OC
Answer: b. Cc1ccc(-c2c(C#N)c(N)n(-c3ccc(C)cc3)c(=O)c2C#N)cc1
