What are the ACID properties in databases, and why are they important for transactions?

ACID describes how a database transaction should behave to keep data reliable and consistent. Atomicity means a transaction is all-or-nothing: either every operation completes and the changes are saved, or if something goes wrong, none of the changes take effect. Consistency ensures that a transaction moves the database from one valid state to another, preserving all defined rules and constraints. Isolation means that when multiple transactions run at the same time, their effects don’t interfere with each other; they behave as if they were executed sequentially. Durability guarantees that once a transaction is committed, its results survive even in the face of crashes or power failures, thanks to reliable storage and logging. Together, these properties ensure that transactions are reliable, changes are not lost or torn, and concurrent access won’t corrupt data. The option that lists Atomicity, Consistency, Isolation, Durability and describes them as ensuring reliable, isolated, and durable transactions is the best fit. Terms like privacy or interruption aren’t part of ACID, so they don’t describe standard transaction guarantees.
