An analyst reviews the following table: Which of the following data types is represented in the values in the RefNo column?

Numeric data is exclusively for values that represent quantities and are used in calculations; RefNo values might contain non-numeric characters or leading zeros, making them unsuitable for a pure numeric type.

Text data, also known as string data, is used for values that contain characters, numbers, and symbols and are not intended for mathematical calculations. Reference numbers often fit this description, as they might include prefixes, leading zeros, or hyphens (e.g., "INV-001", "REF12345"), making them unsuitable for numeric or currency data types and are best stored as text.

Currency data is a specific type of numeric data with associated currency symbols and formatting; RefNo values are identifiers, not monetary amounts.

Alphanumeric data is a subset of text data that specifically refers to characters that are either letters or numbers. While RefNo might be alphanumeric, "Text" is a more general and encompassing data type that allows for other characters (like hyphens) often found in reference numbers, and is typically preferred when values are identifiers rather than quantities for calculation.
