Problem statement: Answer the MCQ question.
Question: Which compound has a 5.438\% 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: CC(=O)c1ccc(N(CC(=O)NCc2ccc3c(c2)OCO3)C(=O)c2csnn2)cc1
b: CN(C)[C@@H]1C(=O)C(C(N)=O)=C(O)[C@@]2(O)C(=O)C3=C(O)c4c(O)cccc4[C@@](C)(O)C3C[C@@H]12.Cl
c: CN(CCOC(=O)c1cccc(Br)c1)C(C)(C)C.Cl
Answer: b. CN(C)[C@@H]1C(=O)C(C(N)=O)=C(O)[C@@]2(O)C(=O)C3=C(O)c4c(O)cccc4[C@@](C)(O)C3C[C@@H]12.Cl
