Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 1.888\% 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.) COc1cc(C(=O)CCC(=O)O)c(OC)cc1C
b.) O=C(Nc1ccc2ccccc2c1)Nc1ccc2snnc2c1
Answer: b. O=C(Nc1ccc2ccccc2c1)Nc1ccc2snnc2c1
