Which of the following is NOT an act that can justify denial of a license?

The choice indicating that seeking employment in unrelated fields does not justify the denial of a license is correct because the law typically focuses on an individual's professional conduct and qualifications directly related to their practice. Optometry licensing boards usually penalize actions that reflect on the individual's moral character or professional competence—such as dishonesty or fraudulent behavior—rather than employment activities outside of the profession.

In contrast, fraudulent application submission, dishonesty in professional conduct, and crimes related to professional duties all demonstrate a lack of integrity or a failure to adhere to professional standards. These actions can directly impact an individual's ability to practice optometry safely and ethically, thus warranting potential denial of their license as they could jeopardize public trust or safety. Engaging in employment unrelated to optometry does not inherently reflect on one's ability to fulfill the responsibilities and ethical obligations required of an optometrist.
