Discussion
A transaction is a series of actions to be taken on the database so that either all of them are performed successfully or none of them are performed at all.
Answer: A
Correct answer: True
This is the definition of a transaction and it is the atomicity property stated in full. The series of actions is treated as a single indivisible unit, so a transfer between two accounts either debits one and credits the other or does neither - the database is never left with the money in neither place.
