Answer:
B. Periodic continuing education
Step-by-step explanation:
The certified safety professional (CSP) exam is a comprehensive examination that tests the knowledge and skills of occupational health and safety specialists. Once an individual has passed the CSP exam and received their certification, they will need to complete periodic continuing education in order to maintain their certification. Continuing education is a requirement for many professional certifications, and it is designed to help professionals stay up-to-date on new developments in their field and maintain their skills and knowledge.
The other options listed in the question do not appear to be requirements for maintaining CSP certification. Option A, yearly community service hours, is not typically a requirement for professional certification. Option C, examination completion every 2 years, is also not a typical requirement. Option D, thirty additional internship hours, may be required in some cases, but it is not specified in the information provided.
