What does it mean for a raw data file to be a delimited data file?

Select one:

a$.$ The file is already in a SAS dataset format s$$ it just needs to be placed in a library for SAS to read it

b$.$ The data values in the file do not have column names associated with them

c$.$ The data values in the file are shortened or "delimited" to save computational time

d$.$ The file is an excel data file

e$.$ The data values in the file are separated by a character string $($delimiter$)$
