The question was posed to me by my college director while I was bunking the class.

The above asked question is from Orientation of Building and House Planning in section Planning of Building and Colony of Civil Engineering Drawing

Answer 1

Right answer is (b) Tubular daylighting device

For explanation: TDDs use modern technology to transmit visible light through opaque walls and roofs. The tube itself is a passive component consisting of either a simple reflective interior coating or a light conducting fiber optic bundle. It is frequently capped with a transparent, roof-mounted dome “light collector” and terminated with a diffuser assembly that admits the daylight into interior spaces and distributes the available light energy evenly (or else efficiently if the use of the lit space is reasonably fixed, and the user desired one or more “bright-spots”).
