Select the correct text in the passage. Which concept explained in the paragraph below means that data always remains consistent?

Specific programs have some A:::tasks that a computer must perform in parallel with others. These tasks (such as the performance of the same set of operations on different data sets) often work in parallel clusters:::. In such cases, a separate thread of execution handles each separate task. B:::You can think of a thread as a sequence of instructions that computers can manage independently.:::

C:::It is possible for different threads to access the same data elements and change their values, and this can lead to an inconsistent state of information.::: For instance, if multiple programs access a shared variable x and change its value, the variable will not contain the correct value at the end of the programs. We can prevent such inconsistencies by using locks. D:::A thread puts a lock on shared data, and releases this lock only after completing its operations.
