Task: Answer the multiple choice question.
Question: Which drug has a 5.729\% 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) Cc1ccc(NC(=O)c2ccc(CNc3c(N4CCOCC4)c(=O)c3=O)cc2)cc1
(b) O=[N+]([O-])c1ccc(C(O)CNC(=S)Nc2ccccc2)cc1
(c) N/C(COc1cccc(Cl)c1)=N\NS(=O)(=O)c1ccccc1
(d) CCn1cc(/C=N/NC(=O)COc2cccc3cccnc23)c2ccccc21
Answer: b. O=[N+]([O-])c1ccc(C(O)CNC(=S)Nc2ccccc2)cc1
