Correct Answer: a, c, b, d

Solution : Given:
(a) Foundation (b) Plastering (c) Building (d) Painting

The construction of a building involves several stages that require careful planning and execution. The first step is laying the foundation, which is critical for ensuring the stability and durability of the structure. Once the foundation is complete, the building structure is erected, which involves assembling the framework, walls, and roof. After the building structure is in place, plastering is done to cover and smooth the surfaces, making them ready for the final step of the construction process - painting. This last step not only adds aesthetic appeal to the building but also serves as a protective layer against weather and wear and tear.

So, the sequence is Foundation, Building, Plastering, Painting or a, c, b, d . Hence, the second option is correct.
