Task: Answer the MCQ question.
Question: Which compound has a -4.856\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CC(Nc1ccccc1CO)C(=O)Nc1cccc(Cl)c1Cl
b: COC(=O)C1=C(C)N(CC2CC2)C(=NCc2cc(OC)c(OC)c(OC)c2)N[C@H]1c1ccccc1
c: CCO[C@H]1OC(C(=O)N2CCOCC2)=C[C@@H](c2ccc(C(F)(F)F)cc2)[C@@H]1CCCO
d: O=S(=O)(O)c1nc2ccccc2n1Cc1ccccc1
Answer: c. CCO[C@H]1OC(C(=O)N2CCOCC2)=C[C@@H](c2ccc(C(F)(F)F)cc2)[C@@H]1CCCO
