An organization with many editors needs to know when features have been created and edited,...

Editor tracking (which records who edited a feature and when) is enabled on individual feature classes or feature datasets in a geodatabase under the Manage menu. Shapefiles do not support editor tracking.

The geodatabase (Option A) controls higher-level administrative functions but not editor tracking.

Shapefiles (Option B) do not support editor tracking.

The feature dataset (Option C) allows enabling editor tracking for included feature classes.

Therefore, the correct answer is C.
