Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.697\% 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, b, c, or d without using any additional words.
Options:
a) CCCC(=O)Nc1nn(C)c2nc3c(C)cccc3cc12
