In the following question, a sentence has been given in the Active voice. Out of the four alternatives, select the one which best expresses the same idea in the Passive voice. Sunita will bake two dozen cupcakes for the bake sale.

Introduction / Context:
This item checks your understanding of how to change a sentence from Active to Passive voice while keeping the same tense, meaning, and emphasis. The original sentence uses the simple future tense and focuses on Sunita as the doer of the action. In the passive version, the focus should shift to the cupcakes while the tense and sense remain intact.

Given Data / Assumptions:

• Active sentence: Sunita will bake two dozen cupcakes for the bake sale.
• Subject: Sunita.
• Object: two dozen cupcakes.
• Tense: simple future (will bake).
• We must form a passive sentence that correctly reflects the same action.

Concept / Approach:
To convert a simple future sentence from active to passive, the structure changes from "will + base verb" to "will be + past participle." The object of the active sentence becomes the subject of the passive sentence, and the original subject is introduced with the preposition "by" if it is mentioned. The time or purpose phrase "for the bake sale" can appear either at the beginning or the end without changing the meaning.

Step-by-Step Solution:
Step 1: Identify the object in the active sentence: "two dozen cupcakes." Step 2: Bring this object to the subject position in the passive sentence. Step 3: Change the verb form "will bake" to the passive pattern "will be baked." Step 4: Retain the agent "Sunita" with the preposition "by." Step 5: Keep the phrase "for the bake sale" in a natural position, for example at the beginning. Step 6: The complete passive sentence becomes: "For the bake sale, two dozen cupcakes will be baked by Sunita."

Verification / Alternative check:
Check tense and meaning carefully. The original sentence talks about a future action. The passive sentence "will be baked" also expresses future time. The number and object (two dozen cupcakes) and the purpose (for the bake sale) remain identical. Thus, the conversion is accurate and faithful to the original.

Why Other Options Are Wrong:

• For the bake sale, two dozen cupcakes are baked by Sunita: Uses present simple "are baked," not the future simple, so the tense changes incorrectly.
• Two dozen cupcakes are being baked by Sunita for the bake sale: Uses present continuous "are being baked," which suggests an action happening now, not a future plan.
• Baking of two dozen cupcakes by Sunita is done for the bake sale: This is an awkward nominal construction with "baking of," and it also suggests a general or habitual action rather than a specific future event.

Common Pitfalls:
A common mistake is to preserve the sense but change the tense, especially in future and modal constructions. Another pitfall is overusing heavy nouns like "baking of" instead of following the straightforward passive structure. Always ensure that the tense marker "will" remains paired correctly with "be" and the past participle when forming the passive voice in future tense.

Final Answer:
The correct passive voice transformation is For the bake sale, two dozen cupcakes will be baked by Sunita.
