Indenting the start and finish of segments 1)requires the new programmers to insert comments o their own 2)requires a lot of extra effort for the programmer 3)makes the flow of the program more difficult to follow 4)makes the flow of the program easier to follow

4)makes the flow of the program easier to follow

Explanation:

When working for companies, lots of people have access to the same code. This means that the code has to be understandable, since we are going to need to use what another programmer has coded to do our part.

A way of making the code undestandable is by indenting the start and the finish of segments, so whoever sees the code will know what is done in that segment.

So the correct answer is:

4)makes the flow of the program easier to follow

Your answer is number 4, or D. Makes the flow of  the program easier to follow.
