Task: Answer the multiple choice question.
Query: Which drug has a 5.463\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] Nc1c(C(=O)NCc2ccco2)c2nc3ccccc3nc2n1CCc1ccc(F)cc1
[b] O=C(NCc1ccco1)c1ccc2c(c1)S(=O)(=O)c1ccccc1C2=O
[c] O=S(=O)(NCc1cccnc1)c1ccc(Cl)nc1
[d] CCC(C)NC(=O)c1ccccc1-c1ccccc1C(=O)NC(C)CC
Answer: b. O=C(NCc1ccco1)c1ccc2c(c1)S(=O)(=O)c1ccccc1C2=O
