Task: Answer the MCQ question.
Query: Which compound exhibits a 4.337\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CCN(c1ccc(OC)cc1)S(=O)(=O)c1csc(C(=O)N2CCCC2)c1
b) COc1ccc(N2CCN(C(=O)COC(=O)CNC(=O)c3ccc(Cl)cc3Cl)CC2)cc1
c) CCO[C@@H]1OC(C(=O)N2CCOCC2)=C[C@H](c2cn(C(C)=O)c3ccccc23)[C@H]1CCCO
Answer: c. CCO[C@@H]1OC(C(=O)N2CCOCC2)=C[C@H](c2cn(C(C)=O)c3ccccc23)[C@H]1CCCO
