Problem statement: Answer the multiple choice question.
Question: Which compound has a 10.534\% human ether-à-go-go related gene (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] CCc1c(C)c(C#N)c2[nH]c3ccccc3n2c1=S
[b] CCN1C(=O)CC(NNC(=O)c2ccccc2)C1=O
[c] CCOC(=O)NCc1ccc(S(=O)(=O)Nc2ccccc2C)cc1
Answer: a. CCc1c(C)c(C#N)c2[nH]c3ccccc3n2c1=S
