Solution
Concept
Uses of a motor grader
Step-by-step solution
1. A motor grader is a finishing machine: levelling, shaping slopes, mixing and spreading, and maintaining dirt roads. 2. It is not meant for heavy excavation (that is for shovels, dozers and scrapers).
Explanation
Graders cut thin layers with their blade and are used for fine grading, not for heavy digging.
Why the other options are wrong
Finishing, shaping slopes and road maintenance are standard grader uses.
Shortcut
Grader = finishing; shovel/dragline = excavation.
Common mistake
Choosing a valid use in an "except" question.
Correct answer: C) heavy excavation
