Step-by-step explanation:
The question asked by the student relates to the factors that influence a consumer's decision-making process when choosing between products, in this case, laptops from Lenovo and HP. The correct answer is c. Consideration set. A consideration set refers to a group of brands or products that a consumer evaluates as options to satisfy a need.
Sarah's contemplation of the Lenovo Ultrabook and the HP Notebook as potential laptop options fall into this realm. It's important to note that while sociocultural, situational, and psychological influences can all play a role in shaping the consideration set itself, the set represents the specific options being considered by the consumer.
