Researchers conducted a study to understand the impact of two different types of exercise on cardiovascular health. Hypothesis A suggests that high-intensity interval training (HIIT) will yield greater improvements in cardiovascular health than moderate continuous exercise (MCE). Hypothesis B posits that MCE will be equally effective as HIIT due to its potential for longer duration and increased calorie burn over sessions. Participants were assigned to one of the two exercise regimens for 12 weeks, followed by cardiovascular health assessments.

Based on these hypotheses, which of the following statements best reflects the differing predictions of the two hypotheses?
