Final answer:
The classification of engineering licensure for which an engineer with one year of boiler experience can qualify varies by state, and typically requires passing examinations and gaining experience after an ABET-accredited engineering degree. Therefore , the correct answer options is b)
Step-by-step explanation:
An engineer with one year of actual boiler experience verified by an affidavit could potentially qualify to take the exam for different classes of engineering licenses, which are highly dependent on the regulations set by the specific state in question. Typically, licensure progression follows from the initial Fundamentals of Engineering (FE) exam, after which one must gain experience to be eligible for the Professional Engineer (PE) exam.
These engineering classifications, which include first class engineer, second class engineer, chief engineer, and special engineer's license, often require varying levels of experience and examination achievements. To determine the specific eligibility for any of these licenses, one would need to refer to the particular state's licensure requirements.
