Problem statement: Answer the multiple choice question.
Question: Which drug has a 21.020\% 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(S(C)(=O)=NC(=O)c2cc(C)on2)cc1
(b) O=S(=O)(NC(=S)NC1CCCCC1)c1ccc(Cl)cc1
(c) C=CCC(C#Cc1ccccc1)N(C)C
(d) CN(CCc1ccccn1)C(=O)c1nn2c(C(F)(F)F)cc(-c3ccco3)nc2c1Cl
Answer: b. O=S(=O)(NC(=S)NC1CCCCC1)c1ccc(Cl)cc1
