Task: Answer the multiple choice question.
Query: Which compound has a -3.201\% 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. CCCCN(C)CCNC(=O)CCn1nc(-c2ccc(C)cc2)ccc1=O
b. COC(=O)C1=C(C)OC(N)=C(C#N)C1c1cc(OC)ccc1OC
c. CCN(C(=O)COC(=O)c1cccc(S(=O)(=O)N2CCOCC2)c1)C1CCS(=O)(=O)C1
d. CC(C)C[C@H]1CN=C(Nc2ccccc2)N1CC1CCC(C(C)(C)C)CC1
Answer: b. COC(=O)C1=C(C)OC(N)=C(C#N)C1c1cc(OC)ccc1OC
