D Correct answer
Explanation

This technical question asks for the definition of defragmentation, with the claimed answer being 'Concatenate fragments of data into contiguous blocks in memory or on a hard drive.' Defragmentation is indeed the process of rearranging fragmented file pieces so they are stored in contiguous (adjacent) blocks on a disk, which improves read/write performance. Option A incorrectly reverses the definition, Option B describes file reassembly after network transfer (not defragmentation), and Option C mentions fragments without explaining the process.
