Which two string types are considered variable?

The correct answer identifies V_String and V_WString as the two variable string types in Alteryx. V_String is a variable-length string data type used to store character data that can be of any size, allowing for efficient storage and processing of data where the length can vary significantly from one record to another.

Similarly, V_WString is the variable-length version of the Unicode string data type, accommodating characters from various languages and ensuring that internationalized text can be represented accurately. This ability to handle strings of varying lengths makes these data types particularly useful in data processing scenarios where the length of the string data is unpredictable.

In contrast, other options might include fixed-length types or types that do not offer the flexibility needed for variable-length string handling. For example, the regular String type has a fixed maximum length, which does not provide the same flexibility as V_String and V_WString.
