Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.851\% 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] COCCOC(=O)C1=C(C)NC2=C(C(=O)CC(C)(C)C2)C1c1cccnc1
[b] CCOc1ccc2oc(-c3ccccc3)c(C(=O)N3CCN(C)CC3)c2c1
[c] C=CCN(CC=C)C(=O)Nc1cc(Cl)ccc1OC
[d] CNC(=O)COC(=O)Cc1ccc(Cl)cc1
Answer: b. CCOc1ccc2oc(-c3ccccc3)c(C(=O)N3CCN(C)CC3)c2c1
