In the following voice change question, choose the option that correctly expresses the sentence “The painter painted the entire bungalow.” in passive voice.

Introduction / Context:
This question tests knowledge of changing a sentence from active voice to passive voice. The original sentence is in the simple past tense and has a clear subject, verb, and object. In many competitive exams, candidates must be able to transform sentences while preserving the original meaning and tense.

Given Data / Assumptions:

• Active sentence: “The painter painted the entire bungalow.”
• Subject: “The painter”.
• Verb: “painted” (simple past form of “paint”).
• Object: “the entire bungalow”.
• We need a passive sentence that keeps the same tense and sense.

Concept / Approach:
In active voice, the subject performs the action. In passive voice, the object of the active sentence becomes the subject of the passive sentence, and the original subject is placed in a prepositional phrase with “by”, if needed. For simple past tense, the passive structure is: was or were + past participle. Therefore, “painted” in passive will be part of “was painted” or “were painted”, depending on the new subject.

Step-by-Step Solution:
Step 1: Identify the object “the entire bungalow” and make it the new subject of the passive sentence. Step 2: Keep the tense as simple past, so choose “was painted” because “the entire bungalow” is singular. Step 3: Place the original subject “the painter” after the past participle in a “by” phrase. Step 4: Combine everything to get: “The entire bungalow was painted by the painter.” Step 5: Compare this structure with the options and select the exact match, which is Option C.

Verification / Alternative check:
Check the tense: the original uses “painted” which is simple past, and the passive form “was painted” is also simple past. Check meaning: both sentences express the same event, but with different emphasis. The passive highlights the bungalow, while still mentioning the painter as the agent. This confirms that the transformation is accurate and complete.

Why Other Options Are Wrong:
Option A: “The entire bungalow is painted by the painter.” uses present tense “is painted”, which changes the time reference and is therefore incorrect. Option B: “Painting of the entire bungalow was done by the painter.” is grammatically possible but it changes the structure noticeably and sounds less natural in exam oriented transformations. The standard transformation keeps closer to the original pattern. Option D: “Painting of the entire bungalow is done by the painter.” again shifts the tense to present, which does not match the original simple past.

Common Pitfalls:
Students sometimes forget to match tense when changing from active to passive. Another frequent error is to form passive sentences using awkward nominal phrases like “painting of” instead of simply transforming the main verb into passive form. For exam purposes, always keep the tense, number, and meaning unchanged and use standard passive structures such as “was painted”, “is built”, “will be done”.

Final Answer:
The correct passive transformation of the sentence is The entire bungalow was painted by the painter.
