Sure,
Answer:
He said to her if he was really that easy to forget.
-> the sentence involved in this direct speech is a question. "he said to her" does not need to be changed. sentence structure of the question needs to be changed, not like your usual indirect speech sentences.
then, add a if after "he said to her". remember, this is a question.
the word in the sentence, "was" is not a modal verb, therefore it will not be changed. however, of course the word place needs to be switched with the pronoun "he", as we're converting it to a sentence and not a question. so, "if he was really that easy to forget".
The voice of the following sentence is in PASSIVE voice. Active voice means that the noun performing the action is stated first before the object. The correct answer is letter "A. Passive". If the sentence is changed into active voice, it would be like this: "The movers moved the sofa into the living room." I hope this helps.
