Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 13.867\% 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.) CC/C(=N\NS(=O)(=O)c1ccc(C)cc1)c1ccco1
b.) Cc1ccc(S(=O)(=O)CCC(=O)Nc2nnc(-c3cccs3)o2)cc1
c.) Cc1cc(=O)n2nc(N3CCCC(C(=O)NC4CCCCC4C)C3)sc2n1
d.) COC(=O)C1=C(C)OC(N)=C(C#N)C1C1CCCCC1
e.) COC(=O)c1sc(=S)n(Cc2ccccc2)c1C
Answer: d. COC(=O)C1=C(C)OC(N)=C(C#N)C1C1CCCCC1
