Which is the complete specification of the state of the world? A. Atomic event B. Complex event C. Simple event D. None of the mentioned

Atomic event
Complex event
Simple event
None of the mentioned

The correct answer is: A. Atomic event

An atomic event is a single, indivisible event that cannot be broken down into smaller events. It is the complete specification of the state of the world at a given point in time.

A complex event is a collection of atomic events that occur together. It is not a complete specification of the state of the world, as it does not specify the order in which the atomic events occurred.

A simple event is an atomic event that does not have any sub-events. It is a complete specification of the state of the world at a given point in time, but it is not a complex event.

None of the mentioned is not a valid answer.
