In this English grammar question on voice, a sentence in the active voice is given about gazing at the stars. Out of the four alternatives, select the option that best expresses the same idea in the passive voice: I gaze at the stars from my balcony.

Introduction / Context:
This problem tests your skill at converting an active sentence in simple present tense into a passive sentence while keeping the same meaning. The original sentence tells us that the speaker regularly gazes at the stars from a balcony. In the passive version, the focus moves to "the stars", which become the subject of the sentence. You must choose the option that follows the rules of passive formation without unnecessarily changing tense or aspect.

Given Data / Assumptions:

• The main verb "gaze" appears in the simple present form "gaze".
• The subject is "I" and the object is "the stars".
• The prepositional phrase "from my balcony" describes the place.
• The sentence expresses a general or habitual action.
• The passive sentence should remain in simple present tense and still mention the balcony and the agent.

Concept / Approach:
To convert a simple present active sentence into passive voice, we use "is / are + past participle". Because "stars" is plural, the correct auxiliary is "are". In passive voice, the object "the stars" becomes the subject. The original subject "I" may be included with "by me" if we want to show the agent. Place expressions like "from the balcony" can be retained with minimal rearrangement. Unlike continuous forms, this sentence describes a regular action, so the simple present passive is appropriate: "The stars are gazed at".

Step-by-Step Solution:
First, identify "the stars" as the object that will serve as the new subject in the passive sentence. Second, recognise that the tense is simple present, so the passive auxiliary must be "are" for the plural noun "stars". Third, create the passive verb phrase "are gazed at" using the past participle of "gaze" and keeping the preposition "at". Fourth, move the original subject "I" to the end of the sentence with the phrase "by me". Fifth, keep the place expression "from the balcony" in a natural position, such as before "by me".

Verification / Alternative check:
The sentence "The stars are gazed at from the balcony by me" presents the same idea as the original, but the focus is now on the stars. The tense is still simple present, expressing a general habit. The agent "me" remains mentioned, and the balcony location is preserved. If you read both sentences side by side, it is clear that they describe the same situation with only a change of focus from the observer to the observed objects.

Why Other Options Are Wrong:
Option A uses present perfect passive "has been done", which changes the tense and uses an unnatural nominal expression instead of a clear passive form. Option B uses present continuous passive "are being gazed at", which suggests an action happening right now rather than a general habit. Option D is an active sentence in present perfect tense and does not implement passive voice at all. Only option C correctly uses "are gazed at" with the stars as the subject and retains the balcony and the agent information in a grammatical way.

Common Pitfalls:
Learners sometimes assume that "gaze at" cannot form a natural passive, but in English many verb and preposition combinations allow passivisation. Another common error is to change tense unnecessarily when moving from active to passive, in this case switching to present perfect or continuous forms. Some students also forget to keep the preposition "at", producing ungrammatical structures like "are gazed the stars". To avoid such mistakes, always keep the tense the same, use "be + past participle", and preserve necessary prepositions from the original sentence.

Final Answer:
The option that correctly expresses the sentence in the passive voice is: The stars are gazed at from the balcony by me.
