Topic: Voice,

Best Answer Explained in Below-:

The sentence "He gave me a pen" is in the simple past tense, indicating that the action of giving occurred at a specific point in the past. To transform this sentence into the passive voice, we must consider both the tense and structure.

The correct passive construction for the sentence is "A pen was given to me by him." Here’s the breakdown:

1. **Subject and Object Swap**: In the active voice, "He" is the subject performing the action, and "a pen" is the object receiving the action. In passive voice, the object becomes the subject, and the subject is introduced with "by."

2. **Tense Matching**: The original sentence is in the past tense, so the auxiliary verb "was" is appropriately used in the passive construction.

3. **Elimination of Other Options**:
- Option B ("A pen is given to me by him") is in the present tense, which does not match the original sentence.
- Option C ("A pen was being given to me by him") implies a continuous action in the past rather than a completed action.
- Option D ("A pen is being given to me by him") is also in the present continuous tense, which fails to reflect the past action.

Thus, option A correctly represents both the meaning and the tense of the original sentence, making it the right choice.
