Answer 1

Explanation:

The structure of a sentence in the passive voice is object+ past participle of the verb + subject. If in the active voice the verb 'has' is used, it is changed to 'has been'. In accordance with these rules, option B is the correct answer where 'has' is correctly changed into 'has been', 'book' is the object, 'forgotten' is the past participle of the verb 'forget' and 'Steven' is the subject.

Options A, C and D are incorrect because they do not adhere to the above-mentioned rules.

Answer 2

Answer:

Angle of deviation (D) is correct answer.
