Task: Answer the multiple choice question.
Question: Which drug has a -2.274\% 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) O=C(NC(=S)Nc1ccc2c(c1)C(=O)c1ccccc1C2=O)c1ccc(F)cc1
(b) O=c1ncn(-c2ccccc2F)c2ncccc12
(c) CCc1ccc(C2CC(=O)N3CN(c4ccccc4)CSC3=C2C#N)cc1
(d) CN(c1ccc(C(=O)Nc2ccccc2C(=O)N2CCCC2)cc1)S(C)(=O)=O
Answer: b. O=c1ncn(-c2ccccc2F)c2ncccc12
