Volley ball have been played by them..

Answer 2

Answer:

Volley ball have been played by them.

Explanation:

Following the structure of passive voice, we will first use the object which is 'volley ball' with no change because it is third person (noun). the verb is of present perfect tense so we will add 'been' between 'have'(helping verb) and 'played'(main verb, past form of play). Now the subject is 'they' (first person, pronoun), so using it at the place of object we will change it to 'them'.

volley ball is played by them.
