Which form of death has occurred in circumstances where rescue is still possible, even though there is no evidence of brain function, the heart has stopped, and breathing has stopped

The answer is Clinical Death.

Explanation:

The form of death that occurs when the heart stops beating and there is no breathing but where rescue is still possible is "Clinical Death".

There is also "Brain Death" where all brain functions stop and there is no reversing it.
