Task: Answer the MCQ question.
Query: Which drug exhibits a 4.660\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: Cc1cc(C)nc(N(C#N)Cc2ccc([N+](=O)[O-])cc2)n1
b: COc1ccc(/C=C2\SC(=O)N(CC(=O)Nc3ccccc3O)C2=O)cc1OC
c: CCO[C@H]1OC(C(=O)N2CCN(Cc3ccc4c(c3)OCO4)CC2)=C[C@@H](c2ccc(Br)cc2)[C@@H]1CCCO
d: Cc1ccc(Cl)cc1NC(=O)CNC(=O)N1CC(=O)Nc2ccccc21
Answer: c. CCO[C@H]1OC(C(=O)N2CCN(Cc3ccc4c(c3)OCO4)CC2)=C[C@@H](c2ccc(Br)cc2)[C@@H]1CCCO
