Task: Answer the MCQ question.
Question: Which drug exhibits a 8.183\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a c1ccc(C(c2ccccn2)c2ccccn2)cc1
b CCOc1ccc(N2C(=O)c3ccc(C(=O)OCC(=O)N(CC)C4CCS(=O)(=O)C4)cc3C2=O)cc1
c COc1cccc(CN(CC2CCCO2)S(=O)(=O)c2ccc(-n3cnnn3)c(OC)c2)c1
d [N-]=[N+]=N[C@@H]1C[C@H](n2ccc(=O)[nH]c2=O)O[C@@H]1CO
e COc1ccc(C2CC(C)=C(C#N)S(=O)(=O)C2C#N)cc1
Answer: d. [N-]=[N+]=N[C@@H]1C[C@H](n2ccc(=O)[nH]c2=O)O[C@@H]1CO
