In this active and passive voice question, change the sentence "My father is going to build a six bedroom bungalow." into the correct passive form.

Introduction / Context:

This question tests your understanding of how to convert a sentence from active voice to passive voice while preserving tense, aspect, and meaning. The original active sentence is "My father is going to build a six bedroom bungalow." You need to rewrite this sentence in passive voice, focusing on the object "a six bedroom bungalow" and expressing the same future plan or intention.

Given Data / Assumptions:

• Active sentence: "My father is going to build a six bedroom bungalow."
• Subject: "My father".
• Verb phrase: "is going to build".
• Object: "a six bedroom bungalow".
• The passive version should bring "a six bedroom bungalow" to the subject position and keep the sense of a future plan.

Concept / Approach:

In English, to form the passive of a sentence like "X is going to build Y", we place Y at the start and use "is going to be built" plus "by X". The phrase "is going to build" indicates a near future plan or intention. In passive voice, we maintain the same structure but insert "be" before the past participle: "is going to be built". The tense remains present form of "to be" plus "going to", and we simply change the focus from the doer to the object of the action.

Step-by-Step Solution:

Verification / Alternative check:

Compare this result with the options. Option D reads "A six bedroom bungalow is going to be built by my father", which matches exactly the structure we obtained. Option A uses "was going to be built", which incorrectly shifts the time reference into the past. Option B ("will have built a bungalow which will have six bedrooms") changes the meaning and even stays active. Option C ("will have been built") moves to a different future perfect passive construction and does not preserve the original "is going to" sense. Therefore, only option D keeps the original tense, intention, and meaning while correctly forming the passive voice.

Why Other Options Are Wrong:

Option A changes the tense to a past reference by using "was going to be built". Option B is active voice and introduces "will have built" and an additional relative clause, rewriting the meaning. Option C uses a future perfect passive "will have been built", which suggests that the bungalow will already be completed by a certain future time, not simply that there is a plan to build it. These changes do not meet the requirement of a straightforward active to passive transformation.

Common Pitfalls:

Students sometimes overlook the need to retain the same tense and aspect and are distracted by complex sounding options like the future perfect. Others forget to include "be" in "going to be built" and may produce incorrect forms such as "is going to built". A good rule is to keep the auxiliary verbs unchanged as far as possible and simply insert "be" before the past participle when moving from active to passive.

Final Answer:

The correct passive voice sentence is A six bedroom bungalow is going to be built by my father.
