Task: Answer the multiple choice question.
Query: Which drug has a 1.662\% 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 COc1ccc(-c2oc(NC(=O)c3ccc(C)cc3)c(C#N)c2-c2ccc(OC)cc2)cc1
b Cc1c(C(=O)N2CCN(c3ccccc3F)CC2)sc2nc(-c3ccccc3)cn12
c Cc1c(Cl)c([N+](=O)[O-])nn1CCCC(=O)Nc1cc(Oc2ccccc2)cc([N+](=O)[O-])c1
Answer: c. Cc1c(Cl)c([N+](=O)[O-])nn1CCCC(=O)Nc1cc(Oc2ccccc2)cc([N+](=O)[O-])c1
