Concept:Alphabetic data refers to data that contains only letters of the alphabet, with no numbers or symbols.
Explanation:Check each option to see whether it is made up entirely of letters.
Option A contains "Bed", which uses only the letters B, e, and d.
Therefore, it is purely alphabetic data.
Option B contains "Ax44jj", which includes the digits 4 and 4.
Because digits are present, it is alphanumeric data, not alphabetic data.
Option C contains "AB+CD", which includes the plus sign "+".
Since a symbol is included, it is not purely alphabetic.
Option D contains "%", which is a special character and not a letter.
Thus, it cannot be alphabetic data.
Only option A has no numbers or symbols.
Answer:A. Bed
