Common mistakes.
- A. Alphanumeric is a general category that includes both letters and numbers, but 'Text' is a more specific and flexible data type implementation in databases and forms that allows for arbitrary character sequences beyond just letters and numbers.
- C. Discrete data represents countable items with distinct values (e.g., number of children), which is unsuitable for email addresses.
- D. Continuous data can take any value within a given range (e.g., temperature, height), which is also unsuitable for email addresses.
