Explanation

A CD-R (Compact Disc Recordable) holds approximately 700–750 MB of data and is among the cheapest writable optical media available, often costing only a few cents per disc. USB drives typically hold far more than 750 MB and cost more. A DVD-R holds 4.7 GB (far exceeding 750 MB). Blu-ray discs hold 25 GB or more and are significantly more expensive. CD-R is the only option that matches both the capacity constraint of 750 MB and the requirement for least cost.
