Which of the following can result in disciplinary action for inspectors?

The correct choice highlights the importance of complying with specific legal requirements related to consumer protection in the inspection industry in Texas. The failure to display the Consumer Protection Notice is a significant violation of regulations meant to safeguard clients' rights and ensure transparency in transactions.

Inspectors are required to prominently display this notice as it informs consumers about their rights and the obligations of inspectors. This requirement is part of broader consumer protection laws aimed at promoting fair and informed real estate practices. Failing to display this notice can lead to disciplinary action because it can undermine the trust and understanding that consumers need to fully engage in real estate transactions.

The other options, while they may involve procedural errors or shortcomings, do not directly carry the same weight of consumer protection violation as failing to display the Consumer Protection Notice. This distinction makes the second choice a priority issue from a regulatory compliance perspective.
