Task: Answer the multiple choice question.
Question: Which drug has a 17.376\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) COc1ccc(CN2CCN(C(=O)c3cccc4ccccc34)CC2)cc1Br
b.) CCCCOC(=O)CSC1=C(C#N)C(c2ccccc2OCC)C(C#N)C(=O)N1
c.) Cc1cccc(N2C(N)=C(C#N)C(C#N)(C#N)C2c2ccccc2)c1
Answer: b. CCCCOC(=O)CSC1=C(C#N)C(c2ccccc2OCC)C(C#N)C(=O)N1
