Question

They took a lot of photos when they were in spain change active voice into passive voice​

Answer 1

An action in a sentence can be represented in two ways, namely active and passive voice.

The passive voice always uses the past participle form of the main verb irrespective of any tense. Only the auxiliary verbs depend upon the sentence given in the active voice.

The correct answer is A)The window is not going to be opened by the teacher.

Option A is correct as the given sentence is in active voice and to transform it into passive voice the subject of the given sentence 

(The teacher) comes in the place of the object and vice versa. Also, as the sentence is in the present continuous tense, 'be' is added.

Options B, C, and D are not correct as the helping verb 'are' cannot be used here as the subject of the transformed sentence is singular, 'be' is missing, and the past participle form of the main verb (open) is not used respectively.
