Task: Answer the multiple choice question.
Query: Which drug has a 5.045\% 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 other words.
Options:
a Cc1ccc(CNC(=O)C2CCC(=O)N(CCc3ccccn3)C2)s1
b O=C(O)c1ccc(Nc2cccc(F)c2)c([N+](=O)[O-])c1
c CC(C)C(OC(=O)c1ccco1)C(=O)NC1CCCCC1
d CC(=O)Nc1ccc(/C=C/c2nc(-c3ccccc3O)n[nH]2)cc1
Answer: c. CC(C)C(OC(=O)c1ccco1)C(=O)NC1CCCCC1
