Final answer:
Buyers often prepare a criteria list when selecting a seller. Criteria are the standards used to evaluate sellers or products, and these standards can vary based on personal or market conditions. An evaluation is a systematic comparison based on criteria, which may include personal preferences.
Step-by-step explanation:
Buyers often prepare a criteria list when selecting a seller to make the process more manageable. The correct answer to the question is 'a) Criteria'. Criteria are the standards or benchmarks that buyers use to evaluate and compare different sellers or products. These standards can vary based on many factors, such as the budget, quality, convenience, or specific needs of the buyer. For example, someone purchasing a computer for gaming might prioritize graphics capabilities and processing speed, while a buyer looking for a family car might prioritize safety and fuel efficiency.
Criteria can vary due to different reasons like personal needs, market conditions, or a change in strategy. For instance, a business purchasing raw materials might adjust its criteria based on fluctuating commodity prices or supply chain reliability. It's important to understand that personal preference is based on individual likes and dislikes, while an evaluation is a more systematic and objective comparison based on set criteria, which may include personal preferences but also considers other factors such as performance, cost, and sustainability.
