Task: Answer the multiple choice question.
Query: Which drug has a -6.974\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=C(COC(=O)c1ccc(Sc2ccccc2)c([N+](=O)[O-])c1)NC1CCS(=O)(=O)C1
[b] COc1ccc(-n2c(SCC(=O)N3CCN(c4ccccc4)CC3)nc3c(c2=O)SCC3)cc1
Answer: b. COc1ccc(-n2c(SCC(=O)N3CCN(c4ccccc4)CC3)nc3c(c2=O)SCC3)cc1
