Task: Answer the multiple-choice question.
Query: Which drug has a 16.539\% 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 additional words.
Options:
a: COC(=O)C1=CN(c2ccc(OC)cc2)C=C(C(=O)OC)C1c1ccc(C)c([N+](=O)[O-])c1
b: O=C(N/N=C/c1cccc(O)c1)c1cc(-c2ccc3c(c2)OCO3)n[nH]1
c: O=C(O)c1cc2cc(Cl)cc(Cl)c2oc1=O
Answer: a. COC(=O)C1=CN(c2ccc(OC)cc2)C=C(C(=O)OC)C1c1ccc(C)c([N+](=O)[O-])c1
