Concept: To convert an active voice sentence to passive voice:
1. The object of the active sentence becomes the subject of the passive sentence.
2. The main verb is changed to its past participle form (V3).
3. The auxiliary verb "to be" is used before the past participle, and its tense should match the tense of the active sentence.
4. The subject of the active sentence becomes the object of the preposition "by" in the passive sentence (or is sometimes omitted if unimportant).
Step 1: Identify the subject, verb, and object of the active sentence
Active sentence: "Deepak writes a story."
Subject: Deepak
Verb: writes (Simple Present Tense, base form "write")
Object: a story
Step 2: Change the object to the subject
The new subject is "A story".
Step 3: Change the verb to the passive form (auxiliary "to be" + past participle)
The active verb is "writes" (Simple Present Tense).
The passive form for Simple Present Tense is: is/am/are + past participle (V3).
The past participle of "write" is "written".
Since the new subject "A story" is singular, we use "is".
So, the passive verb form is "is written".
Step 4: Add the original subject as the object of "by"
The original subject "Deepak" becomes "by Deepak".
Step 5: Combine to form the passive sentence
"A story is written by Deepak."
Step 6: Evaluate the given options
(1) A story is written by Deepak. This is in the Simple Present Passive tense and correctly transforms the active sentence. This is the correct passive form.
(2) A story will be written by Deepak. This is Future Simple Passive. The active sentence is not future tense.
(3) A story was written by Deepak. This is Simple Past Passive. The active sentence "Deepak writes a story" is Simple Present, not Simple Past ("Deepak wrote a story"). While this option is circled in the image, it does not match the tense of the original active sentence.
(4) A story shall be written by Deepak. This is Future Simple Passive (using "shall" which is less common for third person).
The correct passive form for "Deepak writes a story" (Simple Present Active) is "A story is written by Deepak" (Simple Present Passive).
