Answer 1

The Correct Option is C

Step 1: Understanding the Question:
We need to identify the standard storage capacity of a typical CD (Compact Disc) used in computing and audio.


Step 2: Detailed Explanation:
A standard CD-ROM (Compact Disc Read-Only Memory) typically holds a standard maximum storage capacity of 700 MB (Megabytes), which translates to about 80 minutes of uncompressed Red Book standard audio.
While the earliest versions of CDs had a slightly lower capacity of 650 MB (74 minutes of audio), 700 MB quickly became the universally manufactured and accepted standard for CD media worldwide.
Options (A) 600MB and (B) 1000MB do not represent any standard CD capacities.


Step 3: Final Answer:
The standard storage capacity of a CD is 700 MB.
