Which of the following statements does not correspond to branding campaigns in Mercado Libre?

The correct answer is "They are aimed at obtaining an improved investment/revenue ratio (ACOS)" because branding campaigns primarily focus on long-term goals like brand awareness, recognition, and consideration, rather than immediate sales efficiency metrics like ACOS (Advertising Cost of Sales). ACOS is a performance metric more relevant to direct response or sales-focused campaigns. The other options accurately describe branding campaigns: they focus on discovery and consideration (helping customers find and evaluate products), are used for product launches or positioning (establishing a new product or reinforcing an existing one), and generate brand awareness (making consumers familiar with the brand).
