Task: Answer the multiple choice question.
Question: Which drug exhibits a 22.466% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) Cc1sc(N2C(=O)C3C(C2=O)[C@H]2C=C[C@@H]3C2)c(C#N)c1C
b) COC(=O)c1sc2nc3c(cc2c1N)CCCC3
c) Cc1ccc(C(=O)NN2C(=O)/C(=C/c3cn(C)c4ccccc34)SC2=S)cc1
d) O=C(Nc1ccc(Cl)c(Cl)c1)Nc1ccccn1
Answer: b. COC(=O)c1sc2nc3c(cc2c1N)CCCC3
