What method allows you to retrieve the length of a variable that holds a single text value?

The method that allows you to retrieve the length of a variable that holds a single text value is defined by the syntax %Variable.length%. This syntax is used to access the property of a variable directly, returning the number of characters that the text variable contains.

In the context of Power Automate, utilizing the %Variable.length% format is straightforward and intuitive, providing a quick way to obtain the length of any string stored in a variable.

While the other choices may seem plausible, they do not represent the correct syntax or method specific to retrieving the length of a variable. For instance, the Get subtext action is generally used for extracting part of a string rather than determining its length. On the other hand, the Length function is indeed an existing concept in many programming environments but does not represent the syntax employed in Power Automate for length retrieval. Therefore, the %Variable.length% syntax stands out as the correct and most direct answer in this context.
