Which Is the Bigger Unit of Space in a Computer

Multiple Choice

Which is the bigger unit of space in a computer drive's memory, a gigabyte or megabyte?

A) Gigabytes and megabytes are actually equal in size, but they store different types of files. Megabytes are the units in which text is stored; gigabytes are the units in which images are stored. Images are more complex files and therefore bigger, but gigabytes themselves are no larger than megabytes.
B) A gigabyte is larger because it contains the space of one billion bytes whereas a megabyte contains the space of one million bytes.
C) A megabyte is larger because it contains the space of one billion bytes whereas a gigabyte contains the space of one million bytes.
D) Gigabytes and megabytes do not measure the same type of file capacity and are therefore incomparable.
