Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 13.839\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCCn1c(=S)[nH]c2ccc(C(F)(F)F)cc21
