Problem statement: Answer the multiple choice question.
Question: Which drug has a 16.062\% 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) CC1=C(C#N)S(=O)(=O)C(C#N)C(c2ccccc2)C1
(b) COc1cc(C(c2c(C)[nH][nH]c2=O)c2c(C)[nH][nH]c2=O)ccc1OC(C)C
Answer: a. CC1=C(C#N)S(=O)(=O)C(C#N)C(c2ccccc2)C1
