A sentence has been given with a blank to be filled with an appropriate word. Choose the correct alternative: When he reached the construction ______ everything was messed up.

Correct option is D

The correct answer is (d) site. In the context of construction, the correct word is “site”, which refers to a specific location where building, excavation, or any other structural work is taking place. The sentence indicates that the person arrived at a physical location related to construction, hence “site” is the appropriate word.
“Site” as a noun means:
· A location or place where something is built or occurs, especially construction or excavation.
Correct sentence: “When he reached the construction site, everything was messed up.”
This clearly indicates the physical place of activity related to construction.
