Final answer:
FPA stands for Function Point Analysis and is used to measure the size and complexity of a software system based on its functionality.
Step-by-step explanation:
FPA stands for Function Point Analysis. It is a technique used in software engineering to measure the size and complexity of a software system based on its functionality.
Option B is correct. FPA is used to measure the size of the functionality of an Information system. It helps in estimating the effort and cost required for software development and maintenance.
For example, FPA can be used to measure the number of function points in a software system, which can then be used to estimate the development time and resources needed.
