Explanation:
In order to obtain a 'master's degree' in medicine, one needs to 'complete a particular course designed for the study and pass a designated exam.' The duration of the course ranges between the period of 1.5 to 2 years. The exams are conducted on the basis of the content of the course on different intervals and overall, your score must be above a specified limit to get the degree. For a license, certification, or internship, you must undergo training and specialty in the field. Thus, option A is the correct answer.
