Forklaring
The alpha-numeric data is a combination of alphabetic and numeric characters. Let's check each option:
568 - This is numeric data because it contains only numbers.
SS3 - This is alpha-numeric data because it contains both alphabetic characters ("SS") and a numeric character ("3").
10.00 - This is numeric data because it contains numbers and a decimal point, which is still considered numeric.
Twenty-five - This is alphabetic data because it contains only letters and represents a textual representation of the number 25.
So, the alpha-numeric data among the options is "SS3".
