Task: Answer the multiple choice question.
Question: Which compound has a 4.807\% 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 or b without using any additional words.
Options:
a: CNC(=O)/C(C#N)=C\c1ccc(CNS(=O)(=O)c2ccccc2)o1
b: Cc1ccc(NC(=O)CN2C(=O)c3ccccc3S2(=O)=O)c(C)c1
Answer: a. CNC(=O)/C(C#N)=C\c1ccc(CNS(=O)(=O)c2ccccc2)o1
