Which of the following is NOT a ground for losing an embalmer's license?

The option indicating excessive use of social media is not a recognized ground for losing an embalmer's license. State licensing boards typically focus on professional conduct and ethical standards directly related to the practice of embalming, which includes various forms of misconduct such as fraud, criminal convictions related to professional activities, and negligence. These grounds are critical as they directly pertain to how embalmers interact with the public and uphold the integrity of the profession.

In contrast, while the other options directly affect the trustworthiness and professionalism required in funeral services, the use of social media—if not involving illegal or unethical behavior—generally does not fall under the regulatory concerns that would lead to disciplinary action against an embalmer's license. This illustrates that while social media use can certainly impact professional reputation, it does not inherently violate the ethical or legal standards that govern embalming practice.
