Final answer:
The healthy range of curl-ups for 11-year-old females is not explicitly defined in standard guidelines, but aims for approximately 15-10 repetitions. The correct answer is options B.
Step-by-step explanation:
The question asks for the healthy range of curl-ups for 11-year-old females. In physical education, especially in middle school, students often undergo fitness tests to assess their physical abilities compared to standardized healthy ranges. The President's Council on Physical Fitness and Sports provides guidelines indicating that a healthy range for 11-year-old females doing curl-ups (or partial curl-ups) can vary based on several factors including the specific testing protocol used and the individual fitness levels.
However, the options provided don't exactly match the established guidelines, which suggest younger students should aim for about 15-20 repetitions to demonstrate good physical fitness. Therefore, based on the closest matching option, the healthy range would be B) 5-10 Repetitions.
