Problem statement: Answer the MCQ question.
Query: Which compound has a 4.019\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CC(=O)/C(C(=N)N1CCN(c2cccc(Cl)c2)CC1)=C(\C)O
b: Cc1cc(C(=O)CN2C(=O)C(=O)N(C3CCCC3)C2=O)c(C)n1-c1ccc(F)cc1
Answer: a. CC(=O)/C(C(=N)N1CCN(c2cccc(Cl)c2)CC1)=C(\C)O
