Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.571\% 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) COc1ccc(-c2noc(C3CCCN(C(=O)c4ccccc4OC)C3)n2)cc1
b) CC(C)c1nc(N2CCOCC2)c(C#N)c2c1CCCC2
c) CCN1C(N(C)CCc2cccs2)=N[C@@H](c2ccccc2)C(C(=O)OC)=C1C
Answer: b. CC(C)c1nc(N2CCOCC2)c(C#N)c2c1CCCC2
