Explanation

The phrase "those of you who..." is a standard idiomatic expression used to address a specific subgroup within a larger audience. "Those" acts as a demonstrative pronoun referring to the people, and "of" links it to "you". Other options like "these of" or "those in" are grammatically incorrect in this context.
