Final answer:
A measure designed to protect the public from unqualified practitioners is called a regulatory license. The correct answer is option c.
Step-by-step explanation:
A measure designed to protect the public from unqualified practitioners is known as a regulatory license. These are occupational licenses issued by government agencies, which indicate that a worker has completed a certain type of education or passed a certain test.
This form of licensing is often found in professions where the safety and well-being of the public are particularly at stake, such as in medicine, law, engineering, and certain trades. Unlike a revenue license, which is designed to raise money for the government.
A regulatory license serves as a barrier to entry, ensuring that only those who have met specific qualifications and standards can offer certain services. By setting this barrier, it aims to prevent unqualified individuals from practicing in certain fields, thereby protecting consumers from potential harm.
