To answer this question, let's go through each option:
Option A) Durable - This option is correct. In the ACID properties of a database transaction, "D" stands for "Durable". This means that once a transaction is committed, its effects are permanent and will survive any subsequent system failures.
Option B) Different - This option is incorrect. "Different" is not a property in the ACID acronym.
Option C) Decouple - This option is incorrect. "Decouple" is not a property in the ACID acronym.
Option D) Deploy - This option is incorrect. "Deploy" is not a property in the ACID acronym.
The correct answer is A) Durable. This option is correct because in the context of the ACID properties, durability refers to the guarantee that once a transaction is committed, its changes will persist even in the presence of failures.
