Answer: C
The bottom-up approach to software testing begins with the
testing of atomic units, such as programs and modules, and
works upwards until a complete system testing has taken
place. The advantages of using a bottom-up approach to
software testing is the fact that there is no need for stubs
or drivers and errors in critical modules are found earlier.
The other choices in this question all refer to advantages
of a top-down approach which follows the opposite path,
either in depth-first or breadth-first search order.
