involves encoding information using fewer bits than the original representation Group of answer choices

The answer is "Data compression".

Explanation:

In the given question some information is missing, that is the option of the question, which can be described as follows:  

a) Data mining.

b) Information theory.

c) Data compression.

d) Image reconstruction.
