Task: Answer the multiple-choice question.
Query: Which compound exhibits a -1.576% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COc1ccc(CN2CCCC(C(=O)N3CCCCC3)C2)c(OC)c1.O=C(O)C(=O)O
b: O=S(=O)(c1ccc2c(c1)CCN2)N1CCCC1
Answer: b. O=S(=O)(c1ccc2c(c1)CCN2)N1CCCC1
