Answers:
a) Internal
b) Line
c) Program
d) External
e) Block

Answer 1

External documentation is a user-oriented reference guide describing the program's features and usage, different from internal documentation intended for developers.

Step-by-step explanation:

The correct answer to the question is d) External documentation. External documentation is a reference guide designed for users that describes the features and how to use various aspects of a program. Unlike internal documentation, which is written as comments within the code for developers, external documentation is meant to be a helpful resource for end-users who need to understand how to operate the software without looking at the code.

Program documentation can be split into two categories: internal and external. While internal documentation assists developers in maintaining and understanding the software, external documentation assists users. Other types of documentation, such as line and block documentation, also exist but are more related to specific sections or blocks of code within the program, and not the focus of this question.
