Final answer:
C. CD/DVD-ROM. The best storage device for Melanie to copy a home movie to play on her television is a CD/DVD-ROM. However, modern televisions often support USB flash drives or external hard drives,
Step-by-step explanation:
The best storage device for Melanie to copy a home movie that can be played on her television would be a CD/DVD-ROM. An internal hard drive is not typically designed to be easily removed or used with other devices such as a television.
A central processing unit (CPU) is not a storage device, and similarly, a sound card is not applicable for storage purposes. In contrast, a CD or DVD is a form of optical media that can be written to store files, including video content, and is universally compatible with most DVD players and computers.
Notably, while a CD/DVD-ROM is an excellent choice, modern televisions also support other types of storage devices, such as USB flash drives or external hard drives. These storage mediums benefit from having more capacity and faster access times than optical media and can also be a convenient way to play movies on a TV, provided the TV has the necessary USB ports and compatible media playback software.
