Task: Answer the MCQ question.
Question: Which drug exhibits a -8.390% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) Cc1onc(-c2ccccc2)c1C(=O)Nc1nnc(CC(C)C)s1
(b) O=C(CN1C(=O)COc2ccccc21)NCCCN1CCc2ccccc2C1
(c) CCO[C@H]1OC(C(=O)Nc2ccccc2)=C[C@@H](c2ccc(C(F)(F)F)cc2)[C@@H]1CCCO
(d) CC(C)C[C@H](NC(=O)NCc1ccc(Cl)cc1)C(=O)O
Answer: c. CCO[C@H]1OC(C(=O)Nc2ccccc2)=C[C@@H](c2ccc(C(F)(F)F)cc2)[C@@H]1CCCO
