___ are used for identifying different programming entities uniquely within the program.*1 pointKeywordsReserved wordsVariablesIdentifiers

The correct answer is Identifiers.

Explanation:

Identifiers are names given to programming entities such as variables, functions, arrays, classes, etc., to uniquely identify them within a program. They allow programmers to reference these entities in code, enabling more readable and maintainable code. In programming, it is essential to have unique identifiers to prevent confusion between different entities and to promote clarity in the code structure.

• Keywords: These are predefined words in a programming language that have special meanings and cannot be used as identifiers.
• Reserved words: Similar to keywords, these are words that are reserved by the programming language and cannot be redefined or used for other purposes.
• Variables: These are identifiers but are specifically used to store data values.

In conclusion, while keywords and reserved words are specific types of identifiers for the programming language, identifiers broadly encompass all names used to identify programming entities uniquely.
