Answer:
The answer is B. Taking dual enrollment courses.
Step-by-step explanation:
Rigorous coursework is challenging coursework that pushes students to think critically and develop their academic skills. Dual enrollment courses are college-level courses that high school students can take, often for college credit. These courses are typically more challenging than traditional high school courses, and they can help students prepare for the academic demands of college.
The other answer choices are not examples of rigorous coursework.
A class rank in the top half of your class does not indicate the level of difficulty of the courses that you have taken.
Taking the ACT is a standardized test, not a course.
Applying a month before the deadline is a good strategy for college admissions, but it does not indicate the level of difficulty of your coursework.
Therefore, the only example of rigorous coursework is taking dual enrollment courses.
