Which topic involves manipulating text, such as changing case, concatenation, or searching?

• A. Length
• B. String handling
• C. Lower
• D. Logical operators

Answer: (B)

String handling is the idea here. It involves working with text: changing case, concatenating strings, and searching within text. These are ways we manipulate the actual characters in strings, not just measure them or compare booleans. For example, turning a string to uppercase, joining two strings, or looking for a substring are all string-handling operations. In contrast, length is about counting how many characters a string has, which is a property of the string rather than an operation that changes its content, and logical operators deal with true/false decisions rather than text content.
