Final answer:
The correct answer to the question is A) Higher; solving ill-defined problems requires more cognitive effort due to the ambiguity and the need for the problem solver to impose their own structure.
Step-by-step explanation:
Solving ill-defined problems carry a higher 'cognitive load' because of the lack of task constraints, the appropriate answer is A) Higher. When solving such problems, individuals must deal with the ambiguity and uncertainty inherent in the problem statement. This requires them to generate or impose their own structure on the task, which can increase the cognitive resources needed. For example, when presented with a complex, real-world situation without clear goals or solutions, like creating a marketing plan for a completely new product, the problem-solver must identify relevant factors, set objectives, and generate possible approaches, which can be cognitively demanding.
