Answer:
C. Purging
Explanation:
Data Purging in computer storage is a process that permanently erases and remove data from a storage space. Data deleting only removes the shortcut to the data but does not remove the data permanently, and can be easily recovered by an expert. Data purging removes data permanently and also frees up the storage or memory space for other uses. Data purging is relatively inexpensive and can be achieved with some special software tool.
Since the storage provider wants the hard drive back in working condition, data purging is the best option.
