Pick up the true statement from the following: A. Plain ceiling provides the best property diffusing light B. In the absence of beams, it is easier to install piping C. In the absence of beams, it is easier to paint D. All the above

The correct answer is D. All of the above.

A plain ceiling provides the best property diffusing light because it does not have any obstructions that can block or scatter the light. This makes it ideal for rooms where evenly distributed light is desired, such as offices or classrooms.

In the absence of beams, it is easier to install piping because there is no need to work around the beams. This can save time and money, and it can also make the installation process safer.

In the absence of beams, it is easier to paint because there is no need to tape off the beams. This can save time and effort, and it can also give a more finished look to the paint job.
