Problem statement: Answer the multiple choice question.
Query: Which compound has a 15.572\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCS(=O)(=O)C1=NN2C(=N)/C(=C\c3ccc(OC(=O)c4ccco4)c(OC)c3)C(=O)N=C2S1
b: COc1ccc(Cc2nn3c(-c4ccccc4Br)nnc3s2)cc1
Answer: a. CCS(=O)(=O)C1=NN2C(=N)/C(=C\c3ccc(OC(=O)c4ccco4)c(OC)c3)C(=O)N=C2S1
