Task: Answer the multiple choice question.
Question: Which drug has a 1.975\% 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(=O)C2CCCN(Cc3cccn3-c3ccc(Cl)cn3)C2)c(OC)c1
b: COc1cccc(CC(=O)NNC(=O)c2ccc3c(c2)OCO3)c1
c: O=[N+]([O-])c1cc(Cl)cc(/C=N\Nc2ccccn2)c1O
d: COc1ccc(S(=O)(=O)Nc2ccccc2C(=O)N2CCCCC2)cc1C
Answer: b. COc1cccc(CC(=O)NNC(=O)c2ccc3c(c2)OCO3)c1
