Answer:
The correct option is;
It is made of one or more modules.
It breaks a task into simpler and simpler steps.
Explanation:
The implementation of top-down programming approach begins from the system defining basic modules and progresses by putting in place intermediate modules that take charge of more detailed and complex activities and processes. The intermediate modules are further streamlined into more specific programming
Therefore, the top-down programming is made of one or more modules that breaks a task into simpler and simpler steps.
