Wait, can the virtual DOM really be that much faster? Sounds too good to be true!

C sounds off, the virtual DOM doesn't change the web page directly.

I think B is misleading, it doesn't always reflect real-time data.

I vaguely recall something about option D being true, but it feels more like a general statement about learning rather than a direct advantage of the Virtual DOM itself.

I practiced a similar question about the Virtual DOM, and I remember that it helps with performance, so A seems like a strong choice.

I'm not entirely sure, but I feel like option B might be misleading. The Virtual DOM doesn't update every element; it only updates what has changed, right?
