What property of a text is measured by the count of characters?

• A. Upper
• B. Length
• C. Substring
• D. Finding maximum

Answer: (B)

The property being measured is the length of the text—the number of characters it contains. This includes every letter, digit, space, and symbol, so a string like "Hello" has length 5 and "Hi there!" has length 9. Counting characters tells you how long the text is, not its case, a contained sequence, or how large a value is compared to others. For example, a substring is a smaller piece inside the text, not the total count, and preserving or changing case (uppercase vs lowercase) isn’t about how many characters exist. Similarly, finding the maximum is about comparing values, not describing the size of the text.
