Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.139\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COc1ccc(OC)c(NC(=O)Cc2coc3ccc(C)cc23)c1
[b] COC(=O)c1cccc(NC(=O)c2cnccn2)c1
[c] O=C(CCl)NN=C(c1ccccc1)c1ccccc1
[d] CC(=O)OC(C)C[N+](C)(C)C.[Cl-]
Answer: b. COC(=O)c1cccc(NC(=O)c2cnccn2)c1
