My elder brother is playing cricket.
Right Answer is: B
The given sentence is in the Active voice, as the form of the verb (‘is playing’) shows that its subject (‘my elder brother’) was doing something and was ‘active’.
Therefore, it must be changed to the Passive voice, where something could be done by the subject, and it was ‘passive’.
In order to do that,
1. The object of the transitive verb in the Active voice should become the subject of the verb in the Passive voice (‘cricket’ becomes the subject in place of ‘elder brother’).
2. Add the appropriate form of the verb ‘be’ to the sentence and use the past participle of the verb (‘is playing’ is converted to ‘is being played’).
3. Add a ‘by’ followed by the doer of the action.
Thus, the same sentence in the Passive voice is ‘Cricket is being played by my elder brother’.
Hence, option B is the correct answer.
