Answer should be A B E:

- Use the transient keyword in your Apex controllers for variables that aren’t essential for maintaining state and aren’t necessary during page refreshes.
- Limit the data coming back from SOQL calls in your Apex controllers. For example, using AND statements in your WHERE clause, or removing null results
- Taking advantage of pagination with a list controller to present fewer records per page
