Answer 2

“I forgave him for his fault”.

If we change this sentence into passive then the sentence would be transformed in to, “He was forgiven for his faults”.

This occurs as in case of changing active to passive there are is a simple rule to be followed which is that The subject and the object interchange their positions in the sentence.
