Show answer & explanation

Correct answer: D

Mega Byte (MB) — 1,024 KB. Used for photos, short audio files; still too small for storing large collections of videos.

Giga Byte (GB) — 1,024 MB. Useful for single movies (a Full HD movie is roughly 1–5 GB) and programs, but many large videos quickly require more space.

Tera Byte (TB) — 1,024 GB. The common unit for modern consumer hard disks; one terabyte can store hundreds of HD movies or many large 4K videos.

Approximate examples: Full HD movie ≈ 1–5 GB; 4K movie ≈ 20–100 GB. For a library of such videos you should choose multiple terabytes (for example 1 TB, 2 TB, 4 TB) depending on how many videos and other files you need to store. Practical tip: Manufacturers sometimes use decimal definitions (1 TB = 1,000 GB) for marketing, while operating systems may report binary values (1 TiB = 1,024 GiB). For buying decisions, looking at the advertised TB sizes and picking extra capacity for future needs is usually sufficient.
