Question

sanitation and hygiene are also important........... the well - being of society and biodiversity conservation. 1)by 2)from 3)for 4)into .

Answer 1

Sanitation and Hygiene are also important “for” the society.

The right answer is option 3.

Here the word for is the only option that is suitable.

Remaining by, from and into are not the perfect words for this sentence and are not suitable also.

So the right answer will be “for”.
