🧠 Explanation:
The active voice form of “She must be helped by me” is “I must help her.” In active voice, the subject (I) performs the action (help) on the object (her), ensuring clarity and directness. Voice transformation is a key grammar skill, enhancing writing precision in academic or professional contexts. The active form emphasizes the doer, making sentences more engaging. Understanding this shift is vital for clear communication, especially in reports, essays, or instructions, where active voice conveys responsibility and action efficiently, improving readability and impact across diverse writing scenarios.
