The correct choice utilizes the findw function, which is particularly useful when you want to search for entire words within a string. The findw function checks for the presence of a specified word in a character string, accounting for word boundaries defined by a delimiter.

In this context, the function findw(ProductName, 'Shirt', ' ') is searching for 'Shirt' as a standalone word within the ProductName variable, using a space as the delimiter. This ensures that 'Shirt' is recognized only when it is not a substring of another word (for instance, it would correctly identify 'Shirt' but ignore 'Shirts' or 'Shirtdress'). The condition checking if findw returns a value greater than zero confirms that 'Shirt' exists as a standalone word.

This functionality addresses the requirement of the question effectively, making it the appropriate choice. The other options either do not correctly isolate 'Shirt' as a standalone word or utilize functions that are not suitable for this kind of search based on word boundaries.
