Problem statement: Answer the multiple choice question.
Question: Which drug has a 4.649\% 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 additional words.
Options:
a Cc1ccsc1C(=O)NNC(=O)Nc1ccc(Cl)c(Cl)c1
b COc1cc(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)(C)C3)cc([N+](=O)[O-])c1O
c COc1ccc(NC(=O)C(=O)NCCN2CCN(C(=O)c3cccs3)CC2)cc1
d CC(C)=C1C2CCC1C(C(=O)NCc1ccccc1)C2C(=O)O
Answer: b. COc1cc(C2C(C#N)=C(N)OC3=C2C(=O)CC(C)(C)C3)cc([N+](=O)[O-])c1O
