In this English grammar question on voice, a sentence in the active voice is given in the present continuous tense. Out of the four alternatives, select the option that best expresses the same idea in the passive voice: The painters are painting my house.

Introduction / Context:
This question tests conversion of an active present continuous sentence into the corresponding passive form. The original active sentence "The painters are painting my house" describes an action that is happening at the present moment. In passive voice, the focus should be on "my house" as the thing undergoing the action, while the idea of an ongoing process must be preserved. This type of transformation is a standard part of English voice exercises.

Given Data / Assumptions:

• The tense is present continuous, indicated by "are painting".
• The subject is "The painters".
• The object is "my house".
• The action is in progress at the current time.
• The passive sentence should keep the present continuous sense and mention both the house and the painters.

Concept / Approach:
To change present continuous active voice to passive voice, we use the pattern "am / is / are being + past participle". The object "my house" becomes the subject of the passive sentence. Because "house" is singular, we use "is being". The past participle of "paint" is "painted". The original subject "the painters" appears after the verb phrase with "by" to show who is doing the work. The resulting sentence must express that the painting activity is happening right now.

Step-by-Step Solution:
First, identify "my house" as the object that will become the subject of the passive sentence. Second, recognise that the tense is present continuous, so the passive auxiliary for a singular subject is "is being". Third, form the passive verb phrase "is being painted" using the past participle of "paint". Fourth, add the agent phrase "by the painters" after the verb phrase to show who is performing the action. Fifth, assemble the full sentence: "My house is being painted by the painters".

Verification / Alternative check:
The passive sentence "My house is being painted by the painters" clearly indicates that the painting of the house is in progress. The structure "is being painted" matches the present continuous meaning of "are painting". The agent "the painters" is still mentioned, and the focus has shifted to the house itself. When you compare it with the original sentence, you can see that the time, agents, and action all match, with only the grammatical subject and object switched.

Why Other Options Are Wrong:
Option A uses "is being done" and a nominal phrase "Painting of my house", which is grammatically possible but not the straightforward passive transformation that the exam usually expects. Option B changes the tense to past perfect "had painted", losing the ongoing sense. Option C is ungrammatical ("has had been painted") and again changes the tense and aspect. Only option D provides the clear and correct present continuous passive form "My house is being painted by the painters".

Common Pitfalls:
A common mistake is to forget the element "being" in continuous passive forms and write "is painted" instead of "is being painted". Another error is to change the tense to simple past or present perfect because the learner focuses more on the completed result than on the ongoing action. Some students also try to avoid using "by" and end up with incomplete or unclear sentences. To avoid these difficulties, remember that continuous tenses in passive always require a form of "be" plus "being" plus the past participle, and that the tense marker must remain consistent with the original sentence.

Final Answer:
The option that correctly expresses the sentence in the passive voice is: My house is being painted by the painters.
