Task: Answer the multiple choice question.
Question: Which drug exhibits a -15.119\% 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 O=C(NCCc1ccccc1Cl)C1CCC(=O)N(Cc2ccc(Cl)cc2)C1
b CCOC(=O)C1=C(COC(=O)c2ccc(C)s2)NC(=O)NC1C
c CN1CCN(c2nc3c(c(=O)[nH]c(=O)n3C)n2Cc2ccc([N+](=O)[O-])cc2)CC1
Answer: c. CN1CCN(c2nc3c(c(=O)[nH]c(=O)n3C)n2Cc2ccc([N+](=O)[O-])cc2)CC1
