Answer 2

Answer:

His promise has not been kept by him .

Explanation :

•The sentence is in active form . We have to make it to passive form

•The sentence is given in the present perfect tense .

•The subject he will be changed into him as object . And the object his promise is changed to subject in the passive form

•The auxiliary verb used before the subject 'he' used is 'has' . So in the passive form after has we have to add been .

•The main verb in passive form is always written in past form .
