Directions: Select the correct passive form of the given sentence. The Central Board of Secondary Education has launched a new helpline for students.

Explanation

The correct answer is 'A new helpline for students has been launched by the Central Board of Secondary Education .' Key Points In Active Voice , a sentence emphasizes the subject, performing an action. In Passive Voice , a sentence emphasizes the action or the object of the sentence. The given sentence is in the active voice and it is in the present perfect tense . When we convert this sentence into a passive voice , the subject '' The Central Board of Secondary Education '' of the active voice becomes the object , the object '' a new helpline for students '' becomes the subject . The active format " has +V3( launched ) " should be converted into the passive format " has + been + V3 ( launched ) ". Thisis the active and passive voicerule for the present perfect tense . Hence, the correct answer is option 3 . Additional Information Verbs of passive format have a different set of tenses (*V3 - Past participle or Third form of the Verb) as given below in the table: TENSE ACTIVE PASSIVE PASSIVE CONVERSION Football is played by Present Simple He plays football am/is/are + V3 him Present He is playing am/is/are + Football is being played Continuous football being +V3 by him He has played Has/have + Football has been Present Perfect football been+ V3 played by him Present Perfect He has been Not used and Not used and unusual Continuous playing football unusual. Football was played by Past Simple He played football Was/were + V3 him He was playing Was/were + Football was being Past Continuous football being + V3 played by him He had played Had + been + Football had been Past Perfect football V3 played by him Past Perfect He had been Not used and Not used and unusual Continuous playing football unusual Football will be played Future Simple He will play football Will + be + V3 by him He will be playing Not used and Future Continuous Not used and unusual football unusual He will have played Will have been Football will have been Future Perfect football + V3 played by him Future Perfect He will have been Not used and Not used and unusual Continuous playing football unusual Hinglish Active Voice में , एक वाक्य विषय पर जोर देता है, एक क्रिया करता है। Passive Voice में , एक वाक्य वाक्य की क्रिया या वस्तु पर जोर देता है। दिया गया वाक्य active voice में है और यह present perfect tense में है। जब हम इस वाक्य को passive voice में बदलते हैं, तो active voice का subject'The Central Board of Secondary Education' , object बन जाता है और object 'a new helpline for students' , subject बन जाता है। Active format " has +V3( launched ) " को passive format " has + been + V3 ( launched ) " में परिवर्तित किया जाना चाहिए। यह present perfect tense के लिए active and passive voicerule है। अतः सही उत्तर विकल्प 3 है।
