A question will be asked by me identify the voice of the following sentence

The given sentence is in the active voice, as the subject 'They' performs an action 'will ask' against the object 'you'.
If this sentence is changed to passive voice, then the subject is also changed, in order to retain the meaning of the sentence.
So, the object takes the place of the subject and vice versa and the word 'by' is introduced as now the subject receives the action by the object. The verb form of the sentence is also changed from active form to passive.

'Subject (They) + verb (will ask) + direct object (you) + object complement (a lot of questions at the interview)' changes to:
'New subject (You) + verb (will be asked) + object complement (a lot of questions at the interview)'
This can be seen in option A, hence it's the right answer.

Option B: The word 'be' is missing. The complete verb form is 'will be asked', without which the sentence is incomplete in meaning.
Option C: The verbs 'be' and 'being' are both different forms of the verb 'to be'. They cannot be repeated one after the other.
Option D: Similarly, 'being' does not follow 'be'.
Hence options B, C and D are incorrect.
