Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.278\% 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 other words.
Options:
a) O=C1Nc2ccccc2C1Cc1nc2ccccc2c(=O)n1-c1ccccc1
b) CSc1ccc(C#N)cc1NC(=O)c1cccnc1Cl
c) CCC(=O)Nc1ccc(C(=O)Nc2cccc(C)n2)cc1
d) CCCCCCCCCCCCOC1OC(CO)C(O)C(O)C1NC(C)=O
Answer: b. CSc1ccc(C#N)cc1NC(=O)c1cccnc1Cl
