Select the most appropriate option to fill in the blank.
Many developing nations are having a ___________ economy these days.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. booming.
The word "booming" is the most appropriate choice because it describes an economy that is growing rapidly or experiencing significant success, which fits the context of developing nations' economies improving.
The other options don't match as well:
"Boosting" implies an action rather than a description of the economy itself.
"Resounding" and "ringing" typically describe sound or impact, not economic conditions
