The split screen view is synced to support efficient revision comparison.

The split screen view is synced to support efficient revision comparison.

• A. It is always synchronized
• B. It has been synced
• C. It has not been synced
• D. It sometimes synced

Answer: (B)

The main idea is about the timing of the action. Using has been synced expresses that the synchronization happened at some point before now and its effect is that the split screen view is in a synced state now. That ongoing synced state is what supports efficient revision comparison, because the two views stay aligned as you review changes. If you said it is synced, you’d be describing a current state, but the sentence needs to convey that the action occurred and established that helpful synced condition. Saying it has not been synced or sometimes synced doesn't fit the intended meaning as cleanly, because those imply either a failure or an irregular setup, which doesn’t reflect the intended, reliable functionality.
