Step-by-step explanation:
The correct answer is A: They did not carefully interpret their marketing analysis before they launched their campaign.
When Lego expanded its market by creating new products and opening theme parks, they made a misstep by not carefully interpreting their marketing analysis before launching their campaign.
By failing to thoroughly analyze the market, Lego may have missed important insights and opportunities, leading to potential issues with product development, customer targeting, and overall market positioning.
For example, if Lego did not thoroughly understand their target audience's preferences, needs, and demands, they might have created products or opened theme parks that didn't align with what their customers wanted, resulting in a failure to attract and retain customers effectively.
