Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.784\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) CC(C)(C)OC(=O)N1CCCC1C(=O)N1CCc2ccccc21
b.) Cc1ccc(OCc2ccc(Br)cc2)c([N+](=O)[O-])n1
c.) Cc1cc(C)c2nc(C(F)(F)F)c(C#N)c(N)c2c1
