Show answer & explanation
Correct answer: B
Correct answer: Atomicity.
Atomicity says a transaction must be all-or-nothing. Either both debit and credit should happen, or neither should remain applied.
Here only one part of the transfer is completed, so the transaction is partially applied and atomicity is broken.
