Task: Answer the MCQ question.
Question: Which drug exhibits a 30.455\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CNC(=O)c1cc2c(cn1)[nH]c1ccccc12
[b] COc1cccc(C(c2sc3ncnn3c2O)N2CC(C)OC(C)C2)c1
[c] CC(=O)OC(C)[C@H]1CC[C@H]2[C@@H]3CC[C@H]4C[C@@H](OC(C)=O)CC[C@]4(C)C3=CC[C@]12C
Answer: a. CNC(=O)c1cc2c(cn1)[nH]c1ccccc12
