    Answer : Option B

    Explanation :

    The three most commonly used Boolean operators are: AND, OR, and NOT. On the Web, Boolean operators are used in advanced searches to combine search items. For example, an "AND" operator between two words ("football AND television") tells the search engine to find documents that contain both of these words.
