The relationship between public law enforcement and private security has historically faced strain due to several key issues:
Perceived competition (A): Concerns over overlapping roles and professional rivalry.
Borderline responsibilities (B): Unclear jurisdiction or operational boundaries can lead to friction.
Moonlighting policies (C): Concerns about law enforcement officers working off-duty in private roles may create conflicts of interest.
All of these issues contribute to the strained relationship.

Professional development combines education, training, experience, and personal commitment to improve an employee's knowledge, skills, and overall effectiveness. In Human Resource management, these elements are essential for strengthening competencies that employees already possess while also helping them adapt to new responsibilities and changing workplace demands. The main purpose of professional development is not to guarantee higher salaries, push employees toward graduate study, or encourage them to leave their jobs.
Instead, it focuses on enhancing performance, building confidence, and increasing long-term value to the organization. Through continuous learning and applied experience, personnel become more capable, productive, and prepared for advancement. Therefore, option A is correct because professional development primarily sharpens and enhances existing competencies, which is one of the central goals of HR training and career development programs.

Continuity planning involves developing strategies and procedures to ensure that critical infrastructure, processes, and systems continue to function or are restored promptly after a disruption. It includes emergency response, crisis management, recovery, and resumption phases.
Contingent planning (A) is not a standard term.
Resource planning (C) focuses on allocation of resources, not continuity.
Resumption planning (D) is a subset of continuity planning.
