Task: Answer the multiple choice question.
Question: Which compound exhibits a 10.707\% 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(Cn1cnc(Cl)c1Cl)c1ccc(F)cc1
b Cc1ccc(-c2c[nH]c(=S)n2-c2ccccc2)cc1
Answer: a. O=C(Cn1cnc(Cl)c1Cl)c1ccc(F)cc1
