Final answer:
To search for a three-letter word that starts with 't' and ends with 'p', you should use the query 't?p'. The question mark (?) is a wildcard character that can represent any single character.
Step-by-step explanation:
To search for a three-letter word that starts with "t" and ends with "p" you would enter t?p. The question mark (?) is used as a wildcard character to represent any single character in many search engines and database query languages. So, option 1) t?p is correct. In this option, the "t" represents the first letter of the word, the question mark represents any character in the place of the second letter, and the "p" represents the third letter of the word.
