Task: Answer the multiple-choice question.
Question: Which compound exhibits a 13.405\% 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 other words.
Options:
[a] Cc1nn(CC(=O)NCC(C)c2ccccc2)c(=O)c2cc3occc3n12
[b] O=C(Nc1ccc(C(=O)N2CCCc3ccccc32)cc1)c1cccs1
[c] CCCCOc1ccccc1C1C(C(=O)OC)=CN(CC)C=C1C(=O)OC
[d] CCOC(=O)C(O)(C1C(=O)CC(C)(C)CC1=O)C(F)(F)F
Answer: b. O=C(Nc1ccc(C(=O)N2CCCc3ccccc32)cc1)c1cccs1
