Answer :

The typical number of courses required to finish a major can vary depending on the specific major and the institution. However, I can provide you with a general idea of the number of courses commonly needed for a major:

1. Most undergraduate majors typically require around 10 to 15 courses to complete. This means that option B, which states 15 courses, falls within the common range for completing a major.

2. Majors that are more specialized or technical may require more courses to cover the necessary material thoroughly. On the other hand, some majors that are more interdisciplinary or flexible may require fewer courses.

3. It's essential to consult your academic advisor or check your institution's specific major requirements to determine the exact number of courses needed to complete your chosen major.

Therefore, based on the general range of courses needed to finish a major, option B (15 courses) seems to be the most accurate choice among the given options.
