Problem statement: Answer the multiple choice question.
Question: Which drug has a -3.662\% 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 additional words.
Options:
a) CCOC(=O)C1=C(O)CSC1=Nc1ccccc1
b) COc1ccc(CNS(=O)(=O)c2cn(C)c(=O)n(C)c2=O)cc1
c) CC(C)Cn1c(N)c(C(=O)COC(=O)c2ccc(F)cc2)c(=O)n(C)c1=O
d) O=C(COC(=O)c1cnccn1)Nc1cccc2ccccc12
e) CCOC(=O)c1c(NC(=O)c2cc(-c3cccc(O)c3)on2)sc(C(C)=O)c1C
Answer: d. O=C(COC(=O)c1cnccn1)Nc1cccc2ccccc12
