Task: Answer the multiple choice question.
Question: Which compound exhibits a 4.401\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] C=C(C)c1cccc(C(C)(C)NC(=O)NCc2ccncc2)c1
