Task: Answer the multiple-choice question.
Query: Which drug exhibits a 0.266% 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 other words.
Options:
a: CCCc1cc(=O)[nH]c(NCCc2ccccc2)n1
b: O=S(=O)(c1ccccc1)c1nc(-c2ccco2)oc1NCc1cccnc1
Answer: a. CCCc1cc(=O)[nH]c(NCCc2ccccc2)n1
