Task: Answer the multiple choice question.
Question: Which compound exhibits a 12.621\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CC1Cc2cc(/C(O)=C3/C(=O)C(=O)N(CCCn4ccnc4)C3c3cccnc3)ccc2O1
b. CCNc1nn2ccccc2c1/C=C(\C#N)C(=O)OCC
c. COc1ccc(C(=O)NC(=O)COC(=O)C2COc3ccccc3O2)cc1
Answer: b. CCNc1nn2ccccc2c1/C=C(\C#N)C(=O)OCC
