Explanation:

To identify the second largest measurement of RAM from the given options, we first need to understand the hierarchy of memory units and exclude irrelevant units. The standard memory hierarchy from smallest to largest is: Byte < Kilobyte < Megabyte < Gigabyte < Terabyte. Let's list the relevant options in ascending order of size: (c) Byte, (b) Megabyte, (d) Gigabyte, (a) Terabyte. Option (e) Megahertz (MHz) is a unit of frequency, typically used to measure processor speed or bus speed, not memory capacity, so it is irrelevant to memory measurement. Among the valid memory units, Terabyte is the largest. Following Terabyte, the next largest unit is Gigabyte. Therefore, (d) Gigabyte is the second largest measurement of RAM among the given choices.
