What type of photographs must applicants submit if the department cannot access an existing one?

The correct response reflects the protocol established by the Texas DPS Private Security Bureau when processing applications. Applicants are required to submit a photograph only if the department is unable to access an existing image on file. This means that if they already have a valid photo associated with the applicant's records, additional photographs are not necessary.

This policy can help streamline the application process and reduce redundancy, ensuring that applicants are not burdened with unnecessary requirements. Additionally, it aligns with the efficiency goals of the department by minimizing the need for applicants to provide new documentation when it is already available.

In this context, the other options suggest specific types of photographs that could be required, which is not the case when the department has an existing image on file.
