Final answer:
The typical number of courses required to complete a major in the U.S. is about 40 in total for a 120 credit hour degree, with approximately half dedicated specifically to the major. Hence, none of the options accurately reflects this figure.
Step-by-step explanation:
The typical number of courses needed to finish a major varies by institution and the specific program, but for the sake of this question, we will assume a generalized framework. Typically, an undergraduate student will need to complete a range of required and elective courses specific to their major in order to graduate. If we refer to the standard academic structure in the United States, an undergraduate student usually needs to complete around 120 credit hours to earn a bachelor's degree. Given that a standard course is usually worth 3 credit hours, a major would comprise roughly 40 courses. However, not all of these courses are exclusively for the major; they also include general education requirements and electives. The number of courses specifically for a major is typically fewer.
In a scenario where a student is aiming to complete a major with 120 credit hours, and each course is worth 3 credit hours, the breakdown might be as follows: 60 credit hours for general education and electives and 60 credit hours for the major itself. This would mean that 20 courses are typically devoted to the major. Since the multiple-choice options provided do not list this figure, it suggests that the question may have inaccuracies or is based on a different educational system. In any case, none of the given options (A. 15, B. 22, C. 12, D. 10) accurately reflect the standard number of courses required for a major in the common U.S. college system.
