Final Answer:
C. National Association of Customer Service Professionals because for overseeing continuing education classes for customer representatives.
Step-by-step explanation:
Continuing education classes for customer representatives are typically overseen by industry-specific organizations like the National Association of Customer Service Professionals (Option C).
These associations specialize in the field of customer service and often offer training, certification, and continuing education programs tailored to the needs of customer representatives.
They design courses to enhance skills, keep professionals updated on industry trends, and maintain high standards of service. While other entities like the Department of Labor and Employment (Option A) or the Federal Trade Commission (Option D) may have regulatory roles or oversight in different aspects of business and employment, they usually do not specifically manage continuing education programs for customer representatives.
The State Department of Education (Option B) primarily focuses on K-12 education within the state and might not directly handle professional development programs for customer service representatives.
Therefore, the National Association of Customer Service Professionals is the most relevant authority for overseeing continuing education classes tailored to this profession. Hence, therefore option C) is correct.
