Correct

Great job! Error budgets are a measurement of service unreliability.

The inverse of an SLO.

The time it takes to fix bugs.

The time you use to push new releases.

This should not be selected

No, the time spent pushing new releases doesn’t factor into an error budget. (But if you serve more errors during a release, you will certainly burn some of your error budget!)
