B Correct answer
Explanation

In JCL, up to 255 sequential datasets can be concatenated using DD statements. This is a system limitation that has existed in MVS/ESA and subsequent systems. Option C (269) is incorrect and appears to be a confusion with the maximum number of dataset name segments (44 characters) or other limits.
