Answer: C
"The most difficult problem is effectively estimating a
project's slack time and/or resource requirements for
individual tasks or development activities. This commonly is
done through direct software measures (size-oriented
SLOC-source lines of code
KLOC-thousand lines of code) or indirect software measures
(function points-values for number of user inputs, outputs,
inquiries
number of files and interfaces). The other choices are
project management methods and techniques employed that are
dependent on the effectiveness of methods used in deriving
accurate and reliable software development productivity and
performance measures."
