Task: Answer the multiple choice question.
Query: Which compound exhibits a 16.080\% 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) Cn1nnnc1SCC(=O)Nc1ccc(Oc2ccccc2)cc1
b) O=C(Cn1cnc(S(=O)(=O)N2CCCC2)c1)Nc1ccc(OC(F)(F)F)cc1
Answer: b. O=C(Cn1cnc(S(=O)(=O)N2CCCC2)c1)Nc1ccc(OC(F)(F)F)cc1
