In this English grammar question on voice, a sentence in the active voice is given as a yes or no question. Out of the four alternatives, select the option that best expresses the same idea in the passive voice: Does he ever drink tea?

Introduction / Context:
This problem checks your ability to convert an active voice question into a passive voice question. The original active question "Does he ever drink tea?" asks whether he at any time drinks tea. In passive voice, the focus shifts to "tea", while the question form and meaning must remain intact. Such transformations require both an understanding of passive formation and the auxiliary structure used in English questions.

Given Data / Assumptions:

• The tense is simple present, shown by "Does he drink".
• The subject is "he" and the object is "tea".
• The adverb "ever" refers to time and indicates at any time.
• The sentence is in interrogative form, requiring inversion of subject and auxiliary.
• The passive question must preserve the same sense of frequency and the time adverb "ever".

Concept / Approach:
To convert a simple present active question into passive voice, we form the passive "is / are + past participle" and then place the auxiliary before the subject to keep the interrogative pattern. Here, the object "tea" becomes the subject of the passive question. Since "tea" is singular, we use "is". The past participle of "drink" is "drunk". The adverb "ever" is normally placed between the auxiliary and the past participle. The agent is expressed as "by him" at the end of the question.

Step-by-Step Solution:
First, identify "tea" as the object that will become the subject in the passive version. Second, recognise that the tense is simple present, so the passive auxiliary for a singular subject is "is". Third, form the passive verb phrase "is ever drunk", placing "ever" between the auxiliary and the participle. Fourth, add the agent "by him" after the verb phrase to show who might drink the tea. Fifth, maintain the interrogative order by placing "Is" at the beginning of the sentence, followed by "tea".

Verification / Alternative check:
The passive question "Is tea ever drunk by him?" clearly asks whether at any time tea is drunk by that person. It preserves the original meaning and uses the simple present passive structure. The adverb "ever" still modifies the idea of frequency, and the agent "by him" correctly represents the original subject. When you compare it with the active question, you see that only grammatical roles have changed, while the question asked remains the same.

Why Other Options Are Wrong:
Option B uses an overly heavy nominal expression "drinking of tea" and present perfect passive, which distorts the tense and the natural style of a simple question. Option C is still in active voice and changes the meaning into a negative statement with a tag question. Option D mixes a passive construction with a tag "isn't it?" and sounds very unnatural. Only option A follows the correct simple present passive interrogative pattern "Is tea ever drunk by him?".

Common Pitfalls:
Students often forget that questions require inversion of auxiliary and subject in English, leading to incorrect orders such as "Tea is ever drunk by him?". Another mistake is to confuse the past participle "drunk" with the past form "drank". Some learners also try to add extra auxiliaries or change the tense to perfect forms, which is not required here. To avoid these issues, always convert the main clause to passive first, then adjust the word order to match the question form, making sure the tense and adverbs remain the same.

Final Answer:
The option that correctly expresses the sentence in the passive voice is: Is tea ever drunk by him?
