Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 8.644\% 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] O=C(c1ccc([N+](=O)[O-])cc1)N(Cc1ccccc1)c1ccccn1
[b] COc1cc(NC(=O)CSc2nncn2C)c(C)cc1[N+](=O)[O-]
[c] Cc1ccnc(N2C(=O)c3ccc([N+](=O)[O-])cc3C2=O)c1
Answer: a. O=C(c1ccc([N+](=O)[O-])cc1)N(Cc1ccccc1)c1ccccn1
