Task: Answer the multiple choice question.
Question: Which compound has a 3.976\% 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: CC1CCCN(c2nc(NCc3ccco3)nc(N)c2[N+](=O)[O-])C1
b: COc1ccc(CCNC(N)=S)cc1OC
c: CCOC(=O)c1csc(NC(=O)c2ccc(N3C(=O)CCC3=O)cc2)n1
Answer: a. CC1CCCN(c2nc(NCc3ccco3)nc(N)c2[N+](=O)[O-])C1
