I vaguely recall that splitting the data into 40% training and 30% validation might not be ideal for smaller datasets, but I can't remember the specifics.

Okay, let's see. Privacy is about restricting access and keeping information confidential, while security is about protecting the integrity and availability of the data. I think I know which answer choice captures that difference, but I'll double-check to make sure.
