Final answer:
In a hierarchical model of intelligence, tasks from similar categories show higher performance correlations, and tasks at the same hierarchy level correlate similarly, regardless of the ability type.
Step-by-step explanation:
Among the hypotheses consistent with a hierarchical model of intelligence, option b and c are supportive. Specifically, option b, stating that 'If we choose mental tasks from similar categories (e.g., two verbal tasks), the correlation in performance will be higher than the correlation for tasks from different categories,' aligns with the hierarchical model which suggests that similar tasks that fall under the same broad ability would have a higher correlation in performance.
Additionally, option c, which claims that 'Regardless of the ability being assessed (e.g., verbal, quantitative), the correlation in performance between two mental tasks will be the same if selected from the same level of the hierarchy,' is consistent with the hierarchical model because it underscores the idea that at any given level of the hierarchy, tasks will correlate similarly within that level.
