Step 1: Understanding the Concept:
This requires converting an imperative sentence (a request) from active to passive voice.
Step 2: Key Rules for Conversion:
1. Identify the Mood: The word 'Please' indicates that the sentence is a request.
2. Use Standard Passive Phrasing: Imperative sentences starting with 'Please' or 'Kindly' are typically converted to passive voice using the phrase "You are requested to...".
3. Structure the Sentence: The structure is `You are requested to + the rest of the original active sentence (without 'Please')`.
Step 3: Detailed Explanation:
- Active: "Please help me, as I am in need."
- The word 'Please' is replaced by the passive phrase "You are requested to".
- The rest of the sentence, "help me, as I am in need," follows this phrase.
- Passive Sentence: "You are requested to help me as I am in need."
The other options change the meaning. (A), (B), and (C) introduce modals ('must', 'have to', 'may') that are not implied in the original sentence. The phrase 'You are requested to' perfectly captures the politeness of 'Please'.
Step 4: Final Answer:
The correct passive voice is You are requested to help me as I am in need.
