Task: Answer the multiple-choice question.
Question: Which drug exhibits a 11.978\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] Cc1ccc(C2=NO[C@@H]3[C@@H]4C[C@@H]([C@H]5C(=O)N(c6sc7c(c6C#N)CCCC7)C(=O)[C@@H]45)[C@H]23)cc1
[b] Cc1ccccc1-c1nnc(-c2ccc(Cl)cc2)o1
[c] CC(C)=C1SC(N2CCN(c3cccc(C)c3)CC2)=NC1=O
[d] CC(C)(C)NC(=S)NCc1ccco1
Answer: b. Cc1ccccc1-c1nnc(-c2ccc(Cl)cc2)o1
