Answer 1

Hint: Rad the given sentence and understand what ti wants to convey. Now, try to convey the same thing to a third person, in your head. Then go through the options and look for the one which matches to the sentence you just framed in your head or is the closest to it.

Complete answer: Let us first understand what active and passive voices
are. Active voice means that the given sentence has a subject that performs its verb. In short,
This means that the subject is visible or is present in the sentence.
Passive voice means that a subject is in place of an object, i.e. a recipient of a verb’s
action. This means that the subject is not outrightly seen. It is usually there but is
considered invisible. At the end of a passive voice sentence, to make the subject seen,
you just add ‘by someone’. This becomes the default subject.

In order to convert the active voice into passive voice, all you need to do is change the
order of the parts of speech. So, the ‘subject + verb + object’ in the active voice changes to
‘object + verb + (subject)’ in the passive voice.
Now, we know what we are looking for. Let’s look at the given options:
a. The streets were cleaned every day by the workers. - This sentence is in the passive voice as the order has been reversed. It has a completely different tense. So, this is not the required answer. So, this is not the correct option.
b. The workers used to clean the streets every day. - This sentence is still in the active voice, as the order of the parts of speech has not been reversed. This is not the required answer. So, this is an incorrect option.
c. The streets are cleaned every day by the workers. - This sentence is in the passive voice, as the order of the parts of speech has been reversed. The tense is correct. This is the required answer. So, this is the correct option.
d. The workers were cleaning the streets every day. - This sentence is still in the active voice, as the order of the parts of speech has not been reversed. This is not the required answer. So, this is an incorrect option.
Therefore, option c. is correct.

Note: In active voice, the subject performs the action, however, in the passive voice, the subject is placed at the end of the sentence. It is not outrightly visible, nor is it a command.
