A story tells that two friends were walking through the desert. During some point of the journey they had an argument, and one friend slapped the other one in the face. The one who got slapped was hurt, but without saying anything, wrote in the sand : “TODAY MY BEST FRIEND SLAPPED ME IN THE FACE.” They kept on walking until they found an oasis, where they decided to take a bath. The one who had been slapped got stuck in the mire and started drowning, but the friend saved him. After the friend recovered from the near drowning, he wrote on a stone : “TODAY MY BEST FRIEND SAVED MY LIFE.” The friend who had slapped and saved his best friend asked him, “After I hurt you, you wrote in the sand, and now, you write on a stone. Why ?”

The other friend replied : “When someone hurts us, we should write it down in sand where winds of forgiveness can erase it away. But, when someone does something good for us, we must engrave it in stone where no wind can ever erase it.”

What is the synonym of the word ‘engrave’ as used in the passage ?
» Explain it
D
If you engrave something with a design or words, or if you engrave a design or words on it, you cut the design or words into its surface.
 

In the above pic you can see a tree design engraved on a piece of stone.

Similarly, if you inscribe words on an object, you write or carve the words on the object.

Hence 'engrave' and 'insribe' are synonyms and the Option D therefore is the correct answer.
