Task: Answer the MCQ question.
Question: Which compound exhibits a -0.541\% 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. Cn1ccc(C(=O)Nc2ccc(Br)cc2Br)n1
b. CCOC(=O)CSC1=C(C#N)C(c2ccco2)C(C(=O)OCc2ccccc2)=C(C)N1
c. COc1cccc(C(=O)Nc2cc(=O)n(C)c(=O)n2C)c1
d. CC(=O)n1c(-c2ccccc2)c(CO)c2ccccc21
Answer: b. CCOC(=O)CSC1=C(C#N)C(c2ccco2)C(C(=O)OCc2ccccc2)=C(C)N1
