ACID properties are as follows:

  • $A \rightarrow$ Atomicity means to execute all transactions or nothing.
  • $C \rightarrow$ Consistency implies the correctness of the database.
  • $ I \rightarrow$ Isolation means multiple transactions executed without inconsistency.
  • $D \rightarrow$ Durability means data must be recovered in any case of failure.

Option $(A)$ is wrong here. I stand for isolation, not inconsistency.

A similar kind of question was asked in the Gate 2016 set 1
