Task: Answer the MCQ question.
Query: Which compound exhibits a 8.591% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=C(COc1ccccc1)N1CCN(c2ccccc2)CC1
(b) COc1ccccc1C1=NCc2nnc(CSC)n2-c2ccc(Cl)cc21
(c) CCO[C@@H]1OC(C(=O)N2CCOCC2)=C[C@H](c2ccc(Br)cc2)[C@H]1CCCO
(d) CN(C)Cc1ccccc1OC(=O)N(C)C.O=C(O)/C=C/C(=O)O
Answer: c. CCO[C@@H]1OC(C(=O)N2CCOCC2)=C[C@H](c2ccc(Br)cc2)[C@H]1CCCO
