A Correct answer
Explanation

According to the original Red Book CD standard developed by Philips and Sony, standard audio CDs hold 74 minutes of audio. This specification was chosen because it could accommodate Beethoven's Ninth Symphony, which Sony's president insisted should fit on a single disc. Later technology enabled 80-minute and 90-minute discs, but the original specification was 74 minutes. The claimed answer (A) is correct.
