Problem statement: Answer the multiple choice question.
Question: Which drug has a 4.127\% human ether-à-go-go related gene (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 CCN(CC)S(=O)(=O)c1ccc(-c2nnco2)cc1
b O=S1(=O)N=C(N/N=C/c2ccc(Br)o2)c2ccccc21
Answer: a. CCN(CC)S(=O)(=O)c1ccc(-c2nnco2)cc1
