Problem statement: Answer the multiple choice question.
Question: Which drug has a 4.439\% 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: CCC(=O)N1c2ccccc2NC2=C(C(=O)CC(C)(C)C2)C1c1cccnc1
b: COCCCNCCCCOc1ccc(C)cc1[N+](=O)[O-].O=C(O)C(=O)O
c: COc1ccc(CNC(=O)CN2C(=O)CC(c3ccccc3)=Nc3ccccc32)cc1
d: CC(C)(C)Nc1nc(-c2ccccn2)nc2ccccc12
Answer: d. CC(C)(C)Nc1nc(-c2ccccn2)nc2ccccc12
