Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 3.612\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(NC1CCS(=O)(=O)C1)c1ccc(S(=O)(=O)N2CCCCC2)cc1
b: CC(=O)NCCn1c(SCC#N)nc2ccccc2c1=O
Answer: b. CC(=O)NCCn1c(SCC#N)nc2ccccc2c1=O
