Problem statement: Answer the multiple-choice question.
Question: Which compound has a 5.524\% 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) CC(=O)N1c2ccc(S(=O)(=O)N3CCCCC3)cc2CC1C(=O)Nc1cccc(C)c1
b) CN1CC=C2C(C#N)=C(N)C(C#N)(C#N)C(c3cccc(Cl)c3Cl)C2C1
c) O=C(NCCN1CCOCC1)C1CCC(CNS(=O)(=O)c2ccccc2)CC1
d) Cc1ccc2nc(-c3cccc(NC(=O)c4ccco4)c3)[nH]c2c1
Answer: b. CN1CC=C2C(C#N)=C(N)C(C#N)(C#N)C(c3cccc(Cl)c3Cl)C2C1
