Fill in the blank (4) with the appropriate word from the options below:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. all.
The most appropriate word to fill is "all" because the sentence emphasizes the need for sustainable practices across all sectors of the economy, implying a comprehensive approach.
The other options—"every", "some", and "any"—don't convey the same sense of total involvement in all sectors. Therefore, "all" fits best in this context.
