Answer: A

The use of estimation techniques, such as function point
analysis or lines of code estimation, provide a firm basis
for estimation, particularly if supported by historic
records of past activities. An estimate by an experienced
programmer would be the next best option. However, it may be
individualistic and unless there is a standard approach
adopted by the programmer, the estimate can vary
considerably from one programmer to another. Standard
project scheduling tools assist in working out the overall
project schedule, but are reliant on the quality of
estimation of individual tasks. They do not give an estimate
of actual development cost.
