Correct Answer:
C. Insert logo on Slide Master
PowerPoint offers master views to manage consistent elements across multiple slides efficiently. The most efficient method to ensure a company logo appears in the exact same position on all 50 slides is to insert the logo on the Slide Master. The Slide Master is the top-level slide in a hierarchy that controls the theme, layout, background, and common elements for all slides in a presentation. Any object placed on the Slide Master will automatically appear on every slide using that master, ensuring perfect consistency and saving significant time.
- Copy and paste logo to each slide is highly inefficient and prone to alignment errors for numerous slides.
- The Header and Footer dialog box is primarily for text-based headers, footers, dates, and slide numbers, not for positioning images like logos.
- Add logo to slide 1 and duplicate is less efficient than the Slide Master, as it doesn't apply the logo to existing slides without manual intervention or re-duplication.
