Sabrina went to the store for furniture polish,carrots,pencils,ham,sponges,celery,notebook paper,and salami. She remembered to buy all these items by reminding herself that she needed food products that included meats and vegetables and that she needed nonfood products that included school supplies and cleaning aids. Sabrina made effective use of

A) the spacing effect.
B) hierarchical organization.
C) the peg-word system.
D) mood-congruent memory.

Sabrina used hierarchical organization by categorizing her shopping list into two main categories - food products and nonfood products - and then further categorizing each of those into subcategories (meats and vegetables, school supplies and cleaning aids). This is a strategy commonly used to improve memory recall by organizing information into a hierarchy or structure. The other options (spacing effect, peg-word system, and mood-congruent memory) are not relevant to Sabrina's use of organizational strategies for memory recall.
