The correct answer is D. digitization.
Digitization is the process of converting information into a digital format. This can be done with text, images, audio, or video. Digitization can improve efficiency in a number of ways. For example, it can make it easier to store and retrieve information, and it can make it easier to share information with others. Digitization can also make it easier to automate tasks, which can save time and money.

C. evolution is the process of change over time. It is the gradual development of something from a simple to a more complex form.
In the context of the question, digitization is the most likely answer because it is the process that is most likely to lead to efficiency gains. Digitization can improve efficiency in a number of ways, as discussed above.
