Final answer:
The use of an object in unconventional ways represents divergent thinking, which involves generating many potential solutions and is therefore represented by option 'b) Divergent.'
Step-by-step explanation:
Thinking of different uses for an object that aren't normally associated with it is a hallmark of divergent thinking. This type of thinking is about generating creative ideas by exploring many possible solutions. Conversely, convergent thinking involves providing correct or established answers to problems, focusing on narrowing down the multiple possibilities to find the single best solution. Therefore, the answer to the student's question is 'b) Divergent.' Divergent thinking's criteria suit the described situation of thinking of alternative uses for an object, demonstrating creativity and the consideration of numerous potential answers rather than concentrating on one conventional use.
