Answer is Wrong!
Answer is Right!
The correct answer is: B. AND, OR, NOT
Boolean logic is a system of logic that uses the values true and false to represent the outcome of logical expressions. It is used in many different fields, including computer science, mathematics, and philosophy.
The three main search expressions, or operators, recognized by Boolean logic are AND, OR, and NOT.
- AND is used to search for documents that contain all of the specified keywords. For example, if you search for “dog AND cat”, you will find documents that contain both the words “dog” and “cat”.
- OR is used to search for documents that contain any of the specified keywords. For example, if you search for “dog OR cat”, you will find documents that contain either the word “dog” or the word “cat”.
- NOT is used to exclude documents that contain the specified keyword. For example, if you search for “dog NOT cat”, you will find documents that contain the word “dog” but do not contain the word “cat”.
The other options are incorrect because they are not search expressions or operators recognized by Boolean logic.
