Problem statement: Answer the multiple-choice question.
Question: Which drug has a 9.651\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. Cn1c(=O)c2c(nc(CN3CCc4ccccc4C3)n2CC(=O)c2ccccc2)n(C)c1=O
b. CCSc1nc2c(c(=O)[nH]1)C(C(C)C)C(C#N)=C(N)O2
c. O=C(Nc1ccc(C(=O)N2CCN(c3ccccc3)CC2)cc1)C1=CSCCO1
Answer: b. CCSc1nc2c(c(=O)[nH]1)C(C(C)C)C(C#N)=C(N)O2
