Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 7.420\% 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 other words.
Options:
[a] COc1ccc(NC(=S)Nc2cc(-c3ccccc3)[nH]n2)cc1Cl
[b] O=C(Cc1ccc2c(c1)CCCC2)Nc1ccccc1Cl
Answer: b. O=C(Cc1ccc2c(c1)CCCC2)Nc1ccccc1Cl
