Opted Answer: C
Low-level formatting and disk wiping are both methods to erase data on a storage device, but they differ in their approach and effectiveness for data destruction. Low-level formatting is a more thorough process that writes to the physical sectors of the disk, while disk wiping typically involves overwriting data with random patterns. Low-level formatting is more likely to prevent data recovery, especially in older technologies

Overwriting the contents of hard disk multiple times with junk data will ensure that data cannot be recovered.
Throwing in fire is will not be good for environment; destruct hardware; data can be recovered
