Task: Answer the multiple choice question.
Question: Which drug exhibits a -25.027\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) COc1ccc([C@H]2CC(=O)C=C(c3cccc(C#N)c3)C2)cc1
b) O=C(Cn1cc(C(=O)c2ccco2)c2ccccc21)NC1CCCCC1
c) CCCCCC(=O)Nc1cccc(C2=NOC3(C2)C[C@@H](C(N)=O)N(C(=O)Cc2ccc([N+](=O)[O-])cc2)C3)c1
d) Cc1ccc(S(=O)(=O)c2nc(-c3ccccc3Cl)oc2NCCCN2CCOCC2)cc1
Answer: c. CCCCCC(=O)Nc1cccc(C2=NOC3(C2)C[C@@H](C(N)=O)N(C(=O)Cc2ccc([N+](=O)[O-])cc2)C3)c1
