Answer:
b. Find whole words only
Step-by-step explanation:
All Office Package software, to which Power Point belongs, has a feature so you can find a word. In the case of Power Point, you need to click on the "home page" tab and then click on "find" (this button has a binocular symbol). Then you need to check "Find whole words only" and type the word you are looking for (cat). This mechanism prevents the software from finding other words that have "cat" in its composition, such as "catch up". This way the software will find only the word "cat".
