What is the difference, if any, between the end user and the target audience of a digital media piece?

A. The end users and the target audience are the exact same group of people.

B. Some of the target audience may end up as end users if they are rewarded for their participation in the testing phase.

C. End users have nothing to do with the target audience, as they are involved with different parts of the project.

D. Some of the end users are likely also members of the target audience, but not all of them.

Thank you!!
