Problem statement: Answer the multiple choice question.
Question: Which drug has a 5.759\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a COc1ccc(Br)cc1S(=O)(=O)N1CCN=C1C
b CN(Cc1ccccc1)S(=O)(=O)c1ccc2[nH]cc(C(=O)NCC3CCCO3)c(=O)c2c1
Answer: a. COc1ccc(Br)cc1S(=O)(=O)N1CCN=C1C
