Step 1: Understanding the Question:
The task is to convert the given sentence from Active Voice to Passive Voice. The original sentence is in the Present Continuous Tense.
Step 2: Key Formula or Approach:
The structure for converting a Present Continuous sentence from Active to Passive voice is:
\[ \text{Object} + (\text{is/am/are}) + \text{being} + \text{Past Participle (V3)} + \text{by} + \text{Subject} \]
Step 3: Detailed Explanation:
1. Identify Subject, Verb, and Object in the active sentence:
Subject: "The teacher"
Verb: "is correcting" (is + V1 + ing)
Object: "the notebooks"
2. Swap Subject and Object: The object "the notebooks" becomes the new subject.
3. Change the Verb Form: The verb "is correcting" needs to be converted to its passive form. Since the new subject "notebooks" is plural, we use "are". Following the rule, it becomes "are being corrected". The past participle of 'correct' is 'corrected'.
4. Add the Agent: The original subject "the teacher" is added at the end with the preposition "by".
Putting it all together, we get: "The notebooks are being corrected by the teacher."
Step 4: Final Answer:
The correct passive voice conversion is "The notebooks are being corrected by the teacher." This matches option (B).
