Show answer & explanation
Correct answer: A
Concept
For data recorded at a fixed interval, first divide the total duration by the interval to find the number of records.
Multiply that count by the storage per record, then convert units using the stated conversion factor.
Application
Convert 24 hours to seconds: 24 × 60 × 60 = 86,400 seconds.
Find the number of images: 86,400 ÷ 5 = 17,280 images.
Compute storage in megabytes: 17,280 × 1 MB = 17,280 MB.
Convert to gigabytes: 17,280 ÷ 1,024 = 16.875 GB.
Cross-check
Converting back gives 16.875 × 1,024 = 17,280 MB, which equals the storage for 17,280 images at 1 MB each.
Therefore, the required storage is 16.875 GB.
