Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 4.480\% 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 other words.
Options:
(a) CN1CCc2c(sc(NC(=O)c3ccc([N+](=O)[O-])o3)c2C(N)=O)C1.Cl
(b) COc1ccc(COC(=O)NNC(=O)c2ccc(OC)cc2)cc1
(c) CN(C)S(=O)(=O)c1ccc(N2CCCC2)c(C(=O)Nc2nc(-c3ccc(F)cc3)cs2)c1
(d) Cl.c1ccc(C2NCc3ccccc3-n3cccc32)cc1
Answer: a. CN1CCc2c(sc(NC(=O)c3ccc([N+](=O)[O-])o3)c2C(N)=O)C1.Cl
