Problem statement: Answer the multiple choice question.
Query: Which compound has a -21.409% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. Cc1ccccc1OCc1nnc(SCC(=O)Nc2c(C)n(C)n(-c3ccccc3)c2=O)n1-c1ccccc1
b. CCOC(=O)C1=C(c2ccccc2)NC(SC)=C(C#N)C1c1ccco1
c. NNC(=O)/C(=C\c1ccco1)NC(=O)c1ccco1
Answer: b. CCOC(=O)C1=C(c2ccccc2)NC(SC)=C(C#N)C1c1ccco1
