Problem statement: Answer the MCQ question.
Query: Which drug exhibits a -3.834\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CCCC1=C(C(=O)OCC)C(c2ccc(OC)c(C)c2OC)C(C#N)=C(N)O1
b) O=C(NCc1nc2ccccc2[nH]1)C1=C[C@@H](c2ccccc2)C[C@@H](OCCCCO)O1
c) COc1ccc(C2=C(C)C(N3CCN(C(=O)c4ccco4)CC3)=NS2(=O)=O)cc1
d) CCOC(=O)C1CCCc2c1[nH]c1c(C(N)=O)cccc21
Answer: d. CCOC(=O)C1CCCc2c1[nH]c1c(C(N)=O)cccc21
