Step 1: Understanding the Concept:
Land smoothening is a land preparation operation.
Laser technology is used for precision.
Step 2: Key Formula or Approach:
No specific formula.
Need to understand land smoothening practices.
Step 3: Detailed Explanation:
Laser controlled equipment is indeed used for land smoothening operations.
This provides high precision and accuracy.
Land smoothening is done on slopes up to 2-3%, not more than 10%.
If the slope is more than 10%, terracing or other methods are used.
Thus, Statement I is correct, but Statement II is incorrect.
Step 4: Final Answer:
Statement I is correct but Statement II is incorrect.
Hence, the correct option is (C).
