Task: Answer the multiple-choice question.
Query: Which compound exhibits a 8.857\% 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: O=C(c1cc2ccccc2oc1=O)N(Cc1cccc(Br)c1)C1CCS(=O)(=O)C1
b: N#Cc1ccc(C(=O)N(Cc2ccco2)c2c(N)n(Cc3ccccc3)c(=O)[nH]c2=O)cc1
Answer: a. O=C(c1cc2ccccc2oc1=O)N(Cc1cccc(Br)c1)C1CCS(=O)(=O)C1
