make changes to your code ( D )

Explanation:

Variables helps in making it easier to make/effect changes to a code already written. variables are like containers in computing because they are the storage tanks for information that will be referenced or liable to be changed in the future, they help in storing data with a unique name which can be queried when needed to effect changes on the data ( codes ) contained in them.

without Variables data storage would have be difficult to practice because each code after been written and executed will have no backup i.e will be lost and not been able to be modified in future as a reason might arise for that which is either as an error or fr referencing purpose.
