Select the most appropriate option to fill in blank number 2.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. about.
"About" is used to express approximation or near accuracy. It suggests that the number given (15,000) is not exact but close to the actual value.
"There are about 15,000 flowering plants in India" is a natural and commonly used way to describe an estimate, making it the best fit for the blank.
