1. Database: This refers to a structured set of data held in a computer, but it is not typically a character used to identify a data field.

2. File name: This is a label that identifies a file within a filesystem. Again, it does not represent a character used to identify a data field.

3. Label: This typically refers to a character or string that identifies a data field in a program. Labels often describe what type of data is contained in a field.

4. Group: This term usually refers to a collection of data fields but does not itself serve as a character identifier.

The most appropriate option is Label because it directly relates to the identification of data fields in a programming context.
