Wounds go away but deep _____ may turn permanent. Fill in the gap with appropriate words.

Explanation:
Worries, Pain, and Cuts often heal with time while deep scars can be permanent.
Some may argue that worries and pain may not go away in some cases.
But looking at the context of the sentence we can see that it starts with a reference to 'Wounds'.
Hence adding scars to the next half of the sentence seems appropriate

Correct Sentence: Wounds go away but deep scars may turn permanent.
অর্থঃ ক্ষতগুলি চলে যায় তবে গভীর দাগগুলি স্থায়ী হয়ে যেতে পারে।
