Task: Answer the multiple choice question.
Question: Which drug has a 12.929\% 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, or c without using any other words.
Options:
[a] Cc1nnc(SCc2cccc([N+](=O)[O-])c2)s1
[b] CN(Cc1ccc(Cl)s1)C(=O)CNC(=O)CNC(=O)c1ccc(Cl)cc1Cl
[c] CC(=O)c1ccc(N2CCN(c3ccc(S(=O)(=O)N4CCN(C)CC4)cn3)CC2)cc1
Answer: a. Cc1nnc(SCc2cccc([N+](=O)[O-])c2)s1
