Which function would you use to identify a specified section of a text string?

The function that is appropriate for identifying a specified section of a text string is the MID function. This function allows you to extract a substring from a larger string, starting from a specified position for a defined number of characters.

Using the MID function involves three parameters: the text string you want to extract from, the starting position where you want to begin the extraction, and the number of characters you want to retrieve. This is particularly useful when you need to pull out specific information from a larger text, such as extracting the area code from a phone number or finding a particular portion of a description text.

The other functions provided serve different purposes. The RIGHT function is utilized to extract a specified number of characters from the right end of a string. The REPLACE function is used to substitute part of a string with another text. Lastly, the TRIM function is meant to remove extra spaces from the beginning and end of a string. These functions do not serve the purpose of extracting a specific section of text as the MID function does, making it the correct choice for this scenario.
