Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 0.944\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CN(C)/C=C/C(=O)/C=C/c1ccc(Cl)cc1
b: Cc1cccn2c(=O)c(/C=C3\SC(=S)N(CC(C)C)C3=O)c(NCCCOC(C)C)nc12
c: O=C(CCCN1C(=O)/C(=C\c2ccco2)SC1=S)Nc1ccc(O)cc1C(=O)O
Answer: b. Cc1cccn2c(=O)c(/C=C3\SC(=S)N(CC(C)C)C3=O)c(NCCCOC(C)C)nc12
