B. bit; byte
C. megabyte; kilobyte
D. motherboard; peripheral

A. gigahertz; gigabyte

A. gigahertz; gigabyte

The correct answer is A. gigahertz; gigabyte.

To determine the relationship between speed and size, we need to understand the units being referenced.

A. Gigahertz (GHz) measures the speed of a computer's processor, specifically the number of cycles it can perform in one second. This is a measure of speed.

A. Gigabyte (GB) is a unit of measurement for digital storage capacity. It represents 1 billion bytes. This is a measure of size.

Therefore, the relationship between speed and size can be compared by relating gigahertz to gigabyte, giving us the correct answer A. gigahertz; gigabyte.
