Answer 2

Are the kites flown by him these days?

Explanation:  

Whenever the sentence is of the form' the subject doing an action' then the sentence is in active voice. When the sentence is of the form ‘the object need on the subject' then it becomes passive voice.  

Example: Radha painted the wall –Active voice (The subject ‘Radha’ does the action 'paint'). The wall was painted by Radha---Passive voice(action 'paint' done by the subject 'Radha'). In the given question are the kites, the object acted(flown) by the subject ‘him’ changes the sentence in to passive voice.
