Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.684\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COC(=O)Cn1c(=NC(=O)c2cc(OC)cc(OC)c2)sc2cc(OC)ccc21
[b] O=C(Cn1c(=S)[nH]c2ccccc2c1=O)N1CCc2ccccc2C1
[c] O=C(CCC(=O)Nc1ccccc1)NNC(=O)COc1ccccc1
Answer: b. O=C(Cn1c(=S)[nH]c2ccccc2c1=O)N1CCc2ccccc2C1
