Which notation indicates a progressive 720 resolution?

• A. 720i (720 Interlaced)
• B. 720p (720 Progressive)
• C. 1080p (1080 Progressive)
• D. 480p (480 Progressive)

Answer: (B)

Progressive vs interlaced scanning is the key idea. In progressive scanning, each frame is drawn in one pass, giving a full image every time. The letter p stands for progressive, while i stands for interlaced. The number before the letter is the vertical resolution. So 720p means a frame with 720 lines rendered progressively. It’s the notation that specifically signals both the 720-line resolution and the progressive scan method. 720i would be interlaced, not progressive. Other progressive options exist at different resolutions (like 1080p or 480p), but for progressive 720, the notation is 720p.
